Graph and download economic data for Global price of Uranium (PURANUSDM) from Jan 1990 to Jun 2025 about uranium, World, and price.

In December 2024, the global average price per pound of uranium stood at roughly 60.22 U.S. dollars. Uranium prices peaked in June 2007, when it reached 136.22 U.S. dollars per pound. The average annual price of uranium in 2023 was 48.99 U.S. dollars per pound. Global uranium production Uranium is a heavy metal, and it is most commonly used as a nuclear fuel. Nevertheless, due to its high density, it is also used in the manufacturing of yacht keels and as a material for radiation shielding. Over the past 50 years, Kazakhstan and Uzbekistan together dominated uranium production worldwide. Uranium in the future Since uranium is used in the nuclear energy sector, demand has been constantly growing within the last years. Furthermore, the global recoverable resources of uranium increased between 2015 and 2021. Even though this may appear as sufficient to fulfill the increasing need for uranium, it was forecast that by 2035 the uranium demand will largely outpace the supply of this important metal.

The energy segment is estimated to witness significant growth during the forecast period. Uranium plays a crucial role in nuclear power generation, supplying fuel for electricity production in power plants around the world. The global shift towards cleaner energy sources and the rising awareness of carbon footprint reduction have fueled the demand for nuclear power. Nuclear power economics have gained significance, leading to increased investment in uranium production and conversion to uranium hexafluoride for enrichment. Uranium mining continues to be a critical aspect of the industry, with safety, regulation, and sustainability being key considerations. Nuclear power plants require stringent safety measures, including radiation detection and shielding, to ensure reliable operation. Nuclear fuel services provide essential support, from fabrication and licensing to decommissioning and waste management.

Uranium oxide is used in fuel assemblies, while uranium metal is essential for nuclear engineering and innovation. Nuclear power infrastructure development, including construction and technology advancements, continues to drive market growth. Despite the challenges of nuclear power regulation and the presence of nuclear weapons, the industry remains committed to nuclear power safety and security. Uranium enr

If I were to boil the thesis down to a few bullets, I’d say: Uranium is an essential input for nuclear reactors with no substitute. Following the Fukushima disaster, there was a massive supply glut as reactors were taken offline due to safety concerns Now a supply crunch is looming, with a current market deficit of ~40m lbs Nuclear power plants usually contract uranium supplies several years out before their inventory gets run down. Due to the oversupply coming out of the previous cycle, however, they have been purchasing additional supply needs in the spot market instead of contracting years in advance. 13f filings indicate that the power plants’ coverage rates (contracted lbs of uranium supply / lbs of uranium required) are beginning to trend below 100%, indicating utilities have less locked-in supply than they need to keep running their reactors, at a time when market supply is tightening (note utilities typically look to maintain coverage ratios well above 100% to ensure no unforeseen shortfalls) Global demand for uranium is increasing, with ~56 new reactors under construction an a further 99 in planning currently. Nuclear power currently generates ~10% of the world’s electricity but with the closure of coal and fossil fuel power plants due to ESG considerations, nuclear energy is increasingly being seen as the only viable way to make up up the lost energy capacity. Putting all of this together, a fundamental supply/demand imbalance for an essential commodity with price insensitive buyers and ESG tailwinds makes the bull case extremely compelling. But a picture is worth a thousand words, so some historic charts probably best provide a sense of the future upside expected in the next cycle. Using the data of form 8k, at the peak of the previous uranium bull market in 2007 (when there was no supply deficit) the uranium spot price reached ~$136/lb after a run up from ~$15/share at the start of 2004 (~9x increase). Today the current price is ~$42/lb with the view that the price will reach new highs in this coming cycle: Many uranium investors, based on the majority of form 10q, focus on the miners rather than the commodity as being the way to play the new uranium bull market, as these are more levered to price increases in the underlying commodity. The share price for Canadian-based Cameco Corporation (CCO / CCJ, the second largest uranium producer in the world) increased from USD $3/share to $55/share ( ~18x bagger) during the previous bull market from ~2004 – 2007: While Cameco’s performance was impressive, it was not the biggest winner during the previous uranium bull market. Australian miner Paladin Energy ($PALAF) went from AUD $0.01 to AUD $10.70 (~1000x! ) between late 2003 and the market peak in Q1 2007, according to their stock price in Google Sheets: Similar multibagger returns for uranium stocks will be seen again if a new bull market in uranium materializes in the coming 2-3 years when utilities’ uranium supply falls to inoperable levels & they begin contracting again for new supplies. Based on SEC form 4, Paladin in particular is expected to be big winner in any new bull market, as it operates one of the lowest cost uranium mines in the world, the Langer Heinrich mine in Namibia, which was a fully producing mine before being idled in the last bear market. As such, it is a ready-to-go miner rather than a speculative prospect, and so is in a position to immediately capitalise on an uptick in uranium prices and a new contracting cycle with utilities. Given the extent of the structural supply/demand imbalance (which again wasn’t present during the previous bull market) combined with utilities likely becoming forced purchasers of uranium at almost any price, market commentators are forecasting the uranium spot price to reach highs of up to $150/lb, thus enabling the producers to contract at price levels 3x+ the current spot price, driving a massive increase in profitability and cash flows. With some very interesting dynamics and the sprott uranium trust acting as a catalyst, I think the uranium market has the potential to offer a really unique and asymmetric return over the next 2 years.

Despite holding over 30.0% of the world's uranium deposits, Australia accounts for only 8.0% of global uranium production, making it the fourth largest producer. Australia's reserves include the single largest orebody of uranium, located at Olympic Dam, South Australia. The site primarily produces copper, with gold and uranium harvested as byproducts. Currently, the mine, operated by BHP, can produce 4,600 tonnes of uranium, dwarfing that of Four Mile, operated by Heathgate, and Honeymoon, the newly restarted mine owned and operated by Boss Energy. Although domestic production is below that of 2019-20, a surging world price of uranium has provided Australian uranium miners with much-needed growth, elevating revenue at an annualised 9.1% for the five years through 2024-25, including an 8.3% spike in the current year to reach $1.4 billion. The Uranium Mining industry's profitability is highly volatile, so much so that it's commonplace for mines to enter care and maintenance until uranium prices improve. This variability in sale price can result in numerous years of negative profit, where miners elect to stockpile produced uranium to sell it later when prices are more favourable. However, elevated uranium prices have boosted miners' profit margins in recent years. In the coming years, revenue for the Uranium Mining industry is expected to climb at an annualised rate of 15.3% through 2029-30. The ramping up of the Honeymoon mine owned by Boss Energy will drive this growth. Having purchased the site in September 2015, the company has waited until now to restart uranium production following a feasibility study in early 2020 and an updated study 18 months later. With this third Australian mine contributing to domestic production and several proposed mines in Western Australia, the Northern Territory and South Australia, industry revenue is expected to reach $2.7 billion by the end of 2029-30.

Global demand for uranium is forecast to reach *** million pounds of U3O8 by 2035. While demand will be growing constantly, supply of uranium was expected to drop over time. It was forecasted that new assets will be required to fill that supply gap.

LA-ICP-MS uranium-lead geochronologic data of detrital zircon from a metamorphic rock in the northern Fairbanks mining district, Circle Quadrangle, Alaska, Raw Data File 2025-16, provides uranium-lead (U-Pb) geochronologic single spot zircon data, analyzed using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS).

The Maud Belt in Dronning Maud Land (western East Antarctic Craton) preserves a high-grade polyphase tectono-thermal history with two orogenic episodes of Mesoproterozoic (1.2-1.0 Ga) and Neoproterozoic (0.6-0.5 Ga) age. New SHRIMP U-Pb zircon data from southern Gjelsvikfjella in the northeastern part of the belt make it possible to differentiate between a series of magmatic and metamorphic events. The oldest event recorded is the formation of an extensive 1140-1130 Ma volcanic arc. This was followed by 1104 ± 8 Ma granitoids that might represent, together with so far undated mafic dykes, part of a decompression melting-related bimodal suite that reflects the sub-continental Umkondo igneous event. The first high-grade metamorphism is constrained at 1070 Ma. The metamorphic age data are similar to those obtained from other parts of the Maud Belt, but also from the Namaqua-Natal Belt in South Africa, but the preceding arc formation was diachronous in the two belts. This indicates that the two belts did not form a continuous volcanic arc unit as suggested in previous models, but became connected only at the end of the Mesoproterozoic. Intense reworking during the Neoproterozoic, probably as a result of continent-continent collision between components of Gondwana, is indicated by ductile refliation, further high-grade metamorphic recrystallisation and metamorphic zircon overgrowths at approximately 530 Ma. This was followed by late- to post-tectonic magmatism, reflected by 500 Ma granite bodies and 490 Ma aplite dykes as well as a 480 Ma gabbro body.

A comprehensive (mineralogical, geochronological, and geochemical) study of zircons from an eclogitized gabbronorite dike was carried out in order to identify reliable indicators (mineralogical and geochronological) of genesis of the zircons in their various populations and, correspondingly, ages of certain geological events (magmatic crystallization of the gabbroids, their eclogitization, and overprinted retrograde metamorphism). Three populations of zircons separated from two rock samples comprised xenogenic, magmatic (gabbroic), and metamorphic zircons, with the latter found exclusively in the sample of retrograded eclogitized gabbroids. Group I zircons are xenogenic and have a Meso- to Neoarchean age. Mineral inclusions in them (quartz, apatite, biotite, and chlorite) are atypical of gabbroids, and geochemistry of these zircons is very diverse. Group II zircons contain mineral inclusions of ortho- and clinopyroxene and are distinguished for their very high U, Th, Pb, and REE concentrations and Th/U ratios. These zircons formed during the late magmatic crystallization of the gabbroids at temperatures of 1150-1160°C, and their U-Pb age 2389±25 Ma corresponds to this process. Eclogite mineral assemblages crystallized shortly after the magmatic process, as follows from the fact that marginal portions of prismatic zircons contain clinopyroxene inclusions with elevated contents of the jadeite end-member. Group III zircons contain rare amphibole and biotite inclusions and have low Ti, Y, and REE concentrations, low Th/U ratios, high Hf concentrations, contain more HREE than LREE, and have U-Pb age 1911±9.5 Ma, which corresponds to age of overprinted amphibolite-facies metamorphism.

A limiting factor in the accuracy and precision of U/Pb zircon dates is accurate correction for initial disequilibrium in the 238U and 235U decay chains. The longest-lived-and therefore most abundant-intermediate daughter product in the 235U isotopic decay chain is 231Pa (T1/2 = 32.71 ka), and the partitioning behavior of Pa in zircon is not well constrained. Here we report high-precision thermal ionization mass spectrometry (TIMS) U-Pb zircon data from two samples from Ocean Drilling Program (ODP) Hole 735B, which show evidence for incorporation of excess 231Pa during zircon crystallization. The most precise analyses from the two samples have consistent Th-corrected 206Pb/238U dates with weighted means of 11.9325 ± 0.0039 Ma (n = 9) and 11.920 ± 0.011 Ma (n = 4), but distinctly older 207Pb/235U dates that vary from 12.330 ± 0.048 Ma to 12.140 ± 0.044 Ma and 12.03 ± 0.24 to 12.40 ± 0.27 Ma, respectively. If the excess 207Pb is due to variable initial excess 231Pa, calculated initial (231Pa)/(235U) activity ratios for the two samples range from 5.6 ± 1.0 to 9.6 ± 1.1 and 3.5 ± 5.2 to 11.4 ± 5.8. The data from the more precisely dated sample yields estimated DPazircon/DUzircon from 2.2-3.8 and 5.6-9.6, assuming (231Pa)/(235U) of the melt equal to the global average of recently erupted mid-ocean ridge basaltic glasses or secular equilibrium, respectively. High precision ID-TIMS analyses from nine additional samples from Hole 735B and nearby Hole 1105A suggest similar partitioning. The lower range of DPazircon/DUzircon is consistent with ion microprobe measurements of 231Pa in zircons from Holocene and Pleistocene rhyolitic eruptions (Schmitt (2007; doi:10.2138/am.2007.2449) and Schmitt (2011; doi:10.1146/annurev-earth-040610-133330)). The data suggest that 231Pa is preferentially incorporated during zircon crystallization over a range of magmatic compositions, and excess initial 231Pa may be more common in zircons than acknowledged. The degree of initial disequilibrium in the 235U decay chain suggested by the data from this study, and other recent high precision datasets, leads to resolvable discordance in high precision dates of Cenozoic to Mesozoic zircons. Minor discordance in zircons of this age may therefore reflect initial excess 231Pa and does not require either inheritance or Pb loss.

Uraninite geochronology In 2009, uraninite from Coronation Hill was ablated using a 12 m laser beam with the beam rastered along lines at 1 ms-1 to minimise downhole fractionation. Due to the lack of availability of a good uraninite standard isotopic fractionation, mass bias and drift was corrected using the 91500 zircons analysed at the same spot size as the zircons. Experiments were also conducted at smaller spot sizes (4 and 6 m) and showed little or no differences in the U-Pb fractionation at sizes <12 m. Pb-Pb mass fractionation and drift was corrected using NIST610 using a number of line sizes also moving at 1 ms-1. No changes on the Pb isotopes fractionation were observed between different line sizes. The least disturbed uraninite was re-analysed in 2012 using 13 m laser spots bracketed by uraninite from the Kintyre deposit in northern Australia (83735 Ma Cross et al. 2011; 84020 Ma for the combined U-Pb TIMS and Nd-Sm, Maas pers com. 2013) and the Pleisovice zircons (Slama et al. 2008). NIST 610 was analysed with a 60 m spots size to get high count rates for the Pb-Pb mass bias corrections. Data reduction was performed using the same methods as described for zircons but with the Kintyre uraninite as the primary standard. The best results were obtained in December 2012 with an extra low sensitivity tune on the ICPMS to keep U in pulse mode on the detector to avoid accuracy problems associated with the pulse to analogue transition. The age from both sessions was within the uncertainty of the 2009 analytical run and interestingly the Pleisovice zircons also were close to the recommended age when calculated against the uraninite primary standard (although with a large uncertainty due to the low count rates) suggesting that U-Pb down hole fractionation in zircons is similar in both minerals at small spot sizes. The data is presented as U and Pb isotope ratios for individual data points

LA-ICP-MS uranium lead geochronologic data of zircon from igneous and meta-igneous rocks in the Mount Harper project area, Eagle, Tanacross, Mount Hayes, and Big Delta quadrangles, Alaska, Raw Data File 2025-4, provides uranium-lead (U-Pb) geochronologic data from single zircon spots, analyzed using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS). Alaska Division of Geological & Geophysical Surveys (DGGS) staff collected zircon data from 31 samples of igneous and meta-igneous rocks, primarily selected during the 2022 field season in support of the Earth Mapping Resources Initiative (Earth MRI) Mount Harper project. Three of these samples were analyzed to support geologic interpretation in the Taylor Mountain map area. One sample was collected during the 2018 field season in support of the Richardson mining district mapping project, which has since been incorporated into the Mount Harper project area. The goal of this dataset is to determine the age of igneous activity to support geologic mapping efforts, tectonic interpretations, and characterization of mineralization in the Yukon-Tanana Uplands of Interior Alaska. Crystallization age data are organized in the age summary data table with our interpreted crystallization ages, sample location information, and sample descriptions. The zircon grain data table contains isotopic and elemental data for each zircon spot analyzed. Both tables have accompanying data dictionaries. These data and report are available from the DGGS website: http://doi.org/10.14509/31552.

These data are microanalyses of 91 polished thin sections that were examined using a scanning electron microscope (SEM) equipped with an energy dispersive spectrometer (EDS) to identify minerals and observe their relationships at high magnification. Samples are from the Triassic Chinle and Jurassic Morrison Formations and adjacent units, which are the main hosts for sandstone-hosted uranium-vanadium deposits in the Colorado Plateau region. The samples were collected in 2019, 2020, and 2021 from mine dumps and surface mineralized rock at deposits throughout the Colorado Plateau in Utah and Colorado. Samples from New Mexico were from archival drill core and outcropping mineralized rock collected by Alexandra Pearce as part of her dissertation research at the New Mexico Institute of Mining and Technology, Socorro, New Mexico (Pearce, 2020) and were provided to USGS by Dr. Pearce for this study. The spectra for each EDS measurement are provided in separate documents in Portable Data Format (pdf), with one document for each thin section (e.g., BC-20-01B) that was examined. Element spectra were collected at multiple sites within each thin section, and at multiple spots at each site. Sites are arranged in numeric order in the PDF file for each thin section. The separation between sites is marked by a new image of the site showing the numbered spots for each site. For each sample site in the thin sections, three images (BSE, SEI, and MAP) are provided as part of this data release. The images are titled (e.g., BC-20-01B_BSE _001, BC-20-01B_SEI_001 and BC-20-01B_MAP_001), with the sample name (e.g., BC-20-01B) followed by the image type (e.g., SEI or BSE), then site number (e.g., 001). The naming convention for image types is "SEI” for images taken using a secondary electron detector and “BSE” for images taken using the backscattered electron detector. An image “MAP” is also provided for each analyzed site showing the _location of this site on a composite BSE image of the thin section. These thin sections and rock samples are stored in the hot rocks room, Building 810, Denver Federal Center, Lakewood, Colorado, USA. Raw EDS data are saved in the vendor’s proprietary data formats. Visual displays of the EDS spectrum can be saved by the laboratory analyst or ser in any image format or in a MS Word document. Report options exist that will output elemental compositions based on the vendor’s standardless analysis routines. These data are for informational purposes and are not to be used in publication. Quantitative elemental composition by EDS in the DML is not routine and outside the scope of this SOP

Microscopy (Scanning Electron Microscopy, Cathodoluminescence Imaging) and U-Pb isotopic (Secondary Ionisation Mass Spectrometry) analyses of phosphate minerals in a suite of nine L chondrite meteorites (and one reference analysis of an LL chondrite). The dataset includes multiple SIMS spot analyses of phosphates in each meteorite, as well as images at multiple scales of all grains analysed. The data is reported and analysed in Walton et al., 2022 GCA.

This data release compiles the electron microprobe spot analyses of U, Th, and Pb concentrations in uraninite (U oxide) particles, and corresponding calculated age determinations, measured in samples of ore from two uranium-copper breccia pipe ore bodies, the Canyon (Pinyon Plain) and Hack II deposits. The U-rich samples that were analyzed typify the deposits hosted by solution-collapse breccia pipes in the Grand Canyon region of northwestern Arizona. Applying procedures outlined by Bowles (1990), the U, Pb, and Th measurements from each spot analysis were used to calculate a model age for the formation of each uraninite particle. The U, Pb, and Th analyses and calculated age determinations are provided as additional information on the timing and origin of the uranium deposition within the unusual breccia pipe deposits of northwestern Arizona. One of the analyzed samples (CMCH-053-21A) was selected from drill core of a U-Cu ore body of the Canyon deposit, hosted in a solution-collapse breccia pipe. This deposit lies about 750 to 2,000 ft (230 to 610 m) below the surface about 6.1 miles (10 km) south-southeast of Tusayan, Arizona, at latitude 35.88333 North, longitude -112.09583 West (datum WGS 1984). Energy Fuels Inc., owner and operator of the property, conducted extensive drilling into the Canyon deposit, delineating the extent and uranium and copper content of the ore bodies (Mathisen and others, 2017). Mining facilities, including a shaft, have been developed by Energy Fuels at the deposit. The company renamed the Canyon mine as the “Pinyon Plain mine” in 2021. As of October 2021, they await favorable economic conditions to resume mining operations and recover the ore. An earlier-published data release (Van Gosen and others, 2020a) provides the geochemical analyses of 63 elements for 35 drill core samples of the Canyon deposit that were collected by the USGS. X-ray diffraction (XRD) analyses were performed on 28 of these samples to examine their mineralogy; the raw XRD data are provided in Van Gosen and others (2020a). In addition to the XRD analyses, ore mineralogy was also determined by examinations of thin sections of 21 of the ore samples using a scanning electron microscope equipped with an energy dispersive spectrometer (SEM-EDS). The mineralogical analyses are published in Van Gosen and others (2020c). The bulk geochemistry and mineralogy of Canyon deposit sample CHCH-053-21A, analyzed in this study, is provided in Van Gosen and others (2020a, 2020b). The geochemical and mineralogical analysis of ore samples collected from the Hack II deposit, also hosted by a solution-collapse breccia pipe, are published in another data release (Van Gosen and others, 2020b). That data release includes the bulk geochemistry and mineralogy of samples 84-HJW-12 and 84-HJW-3A, which were examined by this study. The Hack II deposit is one of four breccia pipes mined in Hack Canyon near its intersection with Robinson Canyon, approximately 30 miles (48 km) southwest of Fredonia and 9 miles (14.5 km) north-northwest of Kanab Creek, at latitude 36.58219 north, longitude -112.81059 west (datum of WGS84). Mining began at Hack II in 1981 and ended in May 1987. The USGS collected the samples from the Hack II mine in 1984 from underground exposures during active mining. The Canyon and Hack II deposits are representative of numerous other uranium deposits hosted by solution-collapse breccia pipes in the Grand Canyon region of northwest Arizona. These U-Cu deposits occur within matrix-supported, vertical columns of breccia (a "breccia pipe") that formed by solution and collapse of sedimentary strata (Wenrich, 1985; Alpine, 2010). The breccia pipes average about 300 ft (90 m) in diameter and can extend vertically for as much as 3,000 ft (900 m), from their base in the Mississippian Redwall Limestone to as stratigraphically high as the Triassic Chinle Formation. The regions north, south, and east of the Grand Canyon host hundreds of solution-collapse breccia pipes (Van Gosen and others, 2016). Six decades of exploration across the region has found that most of these breccia pipes are not mineralized or substantially mineralized, and only a small percentage of the breccia pipes contain ore-grade uranium deposits. The mineralized breccia pipes contain concentrations of uranium, arsenic, copper, silver, lead, zinc, cobalt, and nickel minerals (Wenrich, 1985), which is reflected in the data sets of Van Gosen and others (2020a, 2020b, 2020c). The Canyon mine sample (CMCH-053-21A) yielded generally consistent age results whether spots were divided by textural type or lumped together. Only those analyses from uraninite as inclusions in chalcopyrite (Cu sulfide) had unusual scatter, possibly due to Pb loss to the sulfide host. The full CMCH-053-21A data set provide a remarkably consistent estimated date at 118.0 ± 4.5 million years ago (Ma) with a mean square of weighted deviates (MSWD) of 0.35 based on 44 of 47 measurements (the low MSWD suggests that the individual errors may have been overestimated). The number after the +/- is one standard deviation of the age in Ma. The Hack II mine sample (84-HJW-12) yielded a wide range of calculated dates. Fine-grained uraninite contained virtually no Pb and gave first-pass model ages all less than 3 Ma. These were not included in further analyses. The remaining 32 analyses, all from uraninite with the droplet-like texture, gave consistently older ages ranging 72 to 233 Ma. Individual droplets or clusters of grains typically gave more coherent age ranges. There was no compelling reason to reject any of these data; however, the aggregate weighted date of 151 ± 16 Ma (MSWD = 12) is probably geologically meaningless. Examination of histograms of the whole data set and an older subset show evidence of several maxima. Grouping of these into younger, intermediate, and older groups is suggestive of coherent age ranges of 112 ± 6, 175 ± 9, and 213 ± 10 Ma, respectively. A second sample from this deposit, 84-HJW-3A, yielded no usable geochronological data on microprobe analysis due to Pb concentrations below detection limits. The microprobe analyses of this sample are included in this data release as the chemical results may be useful.

High- to very-high-grade migmatitic basement rocks of the Wilson Hills area in northwestern Oates Land (Antarctica) form part of a low-pressure high-temperature belt located at the western inboard side of the Ross-orogenic Wilson Terrane. Zircon, and in part monazite, from four very-high grade migmatites (migmatitic gneisses to diatexites) and zircon from two undeformed granitic dykes from a central granulite-facies zone of the basement complex were dated by the SHRIMP U-Pb method in order to constrain the timing of metamorphic and related igneous processes and to identify possible age inheritance. Monazite from two migmatites yielded within error identical ages of 499 +/- 10 Ma and 493 +/- 9 Ma. Coexisting zircon gave ages of 500 +/- 4 Ma and 484 +/- 5 Ma for a metatexite (two age populations) and 475 +/- 4 Ma for a diatexite. Zircon populations from a migmatitic gneiss and a posttectonic granitic dyke yielded well-defined ages of 488 +/- 6 Ma and 482 +/- 4 Ma, respectively. There is only minor evidence of age inheritance in zircons of these four samples. Zircon from two other samples (metatexite, posttectonic granitic dyke) gave scattered 206Pb-238U ages. While there is a component similar in age and in low Th/U ratio to those of the other samples, inherited components with ages up to c. 3 Ga predominate. In the metatexite, a major detrital contribution from 545 - 680 Ma old source rocks can be identified. The new age data support the model that granulite- to high-amphibolite-facies metamorphism and related igneous processes in basement rocks of northwestern Oates Land were confined to a relatively short period of time of Late Cambrian to early Ordovican age. An age of approximately 500 Ma is estimated for the Ross-orogenic granulite-facies metamorphism from consistent ages of monazite from two migmatites and of the older zircon age population in one metatexite. The variably younger zircon ages are interpreted to reflect mineral formation in the course of the post-granulite-facies metamorphic evolution, which led to a widespread high-amphibolite-facies retrogression and in part late-stage formation of ms+bi assemblages in the basement rocks and which lasted until about 465 Ma. The presence of inherited zircon components of latest Neoproterozoic to Cambrian age indicates that the high- to very-grade migmatitic basement in northwestern Oates Land originated from clastic series of Cambrian age and, therefore, may well represent the deeper-crustal equivalent of lower-grade metasedimentary series of the Wilson Terrane.
