Report

This study examines the creation and adoption of OER in the Geosciences with a goal of providing guidance for institutions, libraries and librarians who support and fund OER initiatives. An environmental scan, employed to identify and characterize available college-level OER in this discipline, provided a baseline for the study. Analysis of the scan along with a review of OER, textbook and field guide standards informs a new set of proposed guidelines for Geoscience OER. This work will describe these guidelines and offer a call for community feedback.

It includes numbers describing the results of the analysis and physical properties of groundwater. Time series: The dataset represents a general description of the sample, including name, ID, type of analysis and lab. It includes series of numbers describing the results of the analysis and physical properties of groundwater with associated date. Dynamic values over time at the same sites provides temporal variation data of groundwater composition.

This data package is associated with the publication "Integrated, Coordinated, Open, and Networked (ICON) Science to Advance the Geosciences: Introduction and Synthesis of a Special Collection of Commentary Articles" in Earth and Space Science (Goldman et al. 2022; https://doi.org/10.1029/2021EA002099). The manuscript is an introductory article for a special collection of commentary articles across 19 geoscience disciplines that explore the challenges and opportunities associated with the use of ICON science principles. These principles focus on research intentionally designed to be Integrated, Coordinated, Open, and Networked (ICON) with the goal of maximizing mutual benefit (among stakeholders) and cross-system transferability of science outcomes. This data package contains data, figures, and R scripts associated with the cost/benefit analysis presented in the manuscript. The writing teams involved in the special collection placed each letter of ICON on a plot with perceived cost on one axis and perceived benefit on the other to summarize their perceptions of pursuing each principle of ICON science. These data were subsequently quantified and analyzed. Files are saved as .csv, .R, and .pdf. This data package also contains (1) the public foundational and instructional documents that enabled the crowdsourced creation of the special collection; (2) file-level metadata (flmd) that lists each file in the data package with a description; (3) data dictionary (dd) that defines column headers that appear in csv files. Files are saved as .pdf and .csv.

This simplified map compilation of observations is an attempt to illustrate, in an interpretive and simplified model, the structural complexity in the Howard’s Pass Pb-Zn district. The data for this product were collected and compiled between 2005 and 2012, funded mainly by Selwyn Resources Ltd. and partly by the Northwest Territories Geoscience Office (Strategic Investments in Northern Economic Development program). NWT Open Report 2014-02 contains information on data sources related to this dataset and additional geological interpretation. Recommended Citation: Hodder, R., Bain D.J., and Martel, E. 2014.

The Yukon Digital Geology CD-ROMs present a variety of geoscience data sets in digital format on the geology of the Yukon Territory. They include syntheses of bedrock geology and glacial limits, compilations of geochronology, paleontology, mineral occurrences, oil and gas wells, and a compendium of aeromagnetic images. A subset of a public domain topographic data set (Digital Chart of the World, by ESRI, Inc.) is included for georeference purposes. For ease of use, data sets are divided geographically into 45 map tiles corresponding to the National Topographic System (NTS) 1:250,000 quadrangles. Data sets spanning the entire Yukon Territory are also included for use on sufficiently powerful computers and GIS software. Each theme for all of the 45 map tiles is presented in two projections. An Albers Equal Area projection, on disc 1, is provided to allow seamless integration of adjoining tiles throughout the Yukon. The complete data set is also provided on disc 2 in the UTM coordinate system, which is commonly used for accurately plotting data at the local scale (see Projections). Vector data files are also presented in several different file formats (ArcInfo coverages; Interchange (.e00), dBase (.dbf), shapefiles (.shp), and image data files are presented in band interleaved by line (.bil), and tagged image file format (*.tif) to allow easy importing of data into commercial GIS software. These CD-ROMs also include a limited edition of SurView, a viewing application for Microsoft Windows, developed at the Geological Survey of Canada and originally released as GSC Open File 2661. SurView runs directly off the CD-ROM. It can display, print, and query the *.shp and *.bil files. This provides an opportunity for those without specialized GIS software to delve into the realm of digital geoscience data and explore the Yukon Digital Geology databases on their own PC.

Overview This directory was developed to provide discovery information for anyone looking for publicly accessible repositories that house geological materials in the U.S. and Canada. In addition, this resource is intended to be a tool to facilitate a community of practice. The need for the directory was identified during planning for and follow-up from a drill core repository webinar series in Spring 2020 for public repository curators and staff in the U.S. and Canada hosted by the Minnesota Geological Survey and the Minnesota Department of Natural Resources. Additional supporting sponsors included the U.S. Geological Survey National Geological and Geophysical Data Preservation Program and the Association of American State Geologists Data Preservation Committee. The 10-part webinar series provided overviews of state, provincial, territorial, and national repositories that house drill core, other geoscience materials, and data. When the series concluded a small working group of the participants continued to meet to facilitate the development and production of a directory of repositories that maintain publicly-accessible geological materials throughout the U.S. and Canada. The group used previous directory efforts described in the next section, Summary of Historical Repository Directory Compilation Efforts, as guides for content during development. The working group prepared and compiled responses from a call for repository information and characterization. This directory is planned to be a living resource for the geoscience community with updates every other year to accommodate changes. The updates will facilitated through versioned updates of this data release.

The Queensland Resources Industry Development Plan (QRIDP) was created by government, industry and communities. It sets out a pathway for a resources industry that will continue to create jobs and prosperity for generations to come—responsibly and sustainably. The QRIDP was announced in April 2021, among the 6 focus areas there was a $20 Million investment in precompetitive geoscience programs and circular economy research for the mining industry as well as $22.6 Million invested in Queensland's Collaborative Exploration Initiative.

Action #2- Collaborative Exploration Initiative.

The Collaborative Exploration Initiative (CEI) aims to encourage the discovery and development of Queensland's critical mineral deposits to help meet the growing demands of the world's technology and renewable energy sectors. Funding is currently provided under the Queensland Resources Industry Development Plan (QRIDP), with $17.5 million available until June 2027 to support Queensland's exploration companies to discover the future mines to produce the minerals and metals that the world needs.

• CEI Round 7 - Round 7, which ran from April to December 2023, supported 25 projects – with all data collected through these projects now freely available to access here
• CEI Round 8 - Round 8 is in progress, with projects due to be completed by December 2024. Final reports will be made available from 16th June 2025.
• CEI Round 9 - Opening soon, successful applicants to be awarded 1 April 2025

Action #3 - Geophysics for Discovery

The Queensland Government has invested $10 million in geophysical data such as aeromagnetics, gravity, and magnetotellurics, which are essential for the discovery of mineral systems underground (such as the majority of those in outback Queensland), to help build a picture for developers and investors.

• Regional Gravity - A regional airborne gravity gradiometry (AGG) survey, with line spacing at 1km or better, was discussed as a high priority for mineral explorers based on feedback collected by the GSQ. The Etheridge AGG survey was flown in April-May 2024 and covered over 32,000 sq km in the Georgetown region.

• Regional Magnetics - A regional airborne magnetic and radiometric survey was conducted in the Georgetown region survey to continue to grow the coverage of high resolution magnetics and radiometric data available across prospective regions in Queensland. The Einasleigh airborne geophysics survey has been completed with data due to be released in mid 2024.

• Regional AEM - A regional Airborne Electromagnetic (AEM) survey with a line spacing of 2km will improve the data density within the 20km spaced AusAEM and provide explorers with a much higher resolution dataset to enable area selection and targeting under cover. This survey will be conducted in the Georgetown region in mid 2024 with data to be released by end of 2024.

• AusAEM - GSQ contribution to Geoscience Australia's AusAEM airborne electromagnetic survey in Queensland. AusAEM is the world's largest AEM survey ever undertaken, and extends across the Australian continent. AEM allows mapping of the subsurface electrical conductivity of rocks, sediments and waters, and can aid in the identification of electrically conductive minerals such as sulfides. The 2024 AusAEM program will be flown in mid 2024 and will extend current AusAEM coverage to the east, data will be released late 2024

• Petrophysics Data - This project involves the collection and processing of petrophysics with CSIRO's Mobile Petrophysics Lab along key reference core selected by the GSQ Minerals systems team and the integration with other analytical data. Data and reports will be released on the open data portal

• AusLAMP - GSQ contribution to Geoscience Australia's AusLAMP magnetotelluric survey in Queensland. AusLAMP is a long-period MT survey that images the electrical conductivity structure of the Autralian continental lithosphere in three dimensions and aims to identify and characterise major geological structures in the crust. These structures may be related to zones of prospective mineralisation in the upper crust. Data for all AusLAMP sites collected in Queensland can be found on the Geoscience Australia website.

• Gravity AFGN Update - Increased demand for gravity data acquisition from Industry requires that these surveys can be tied into the national gravity compilation. Revisiting AFGN sites to ensure they are still functional and establishing new sites in areas of demand will ensure gravity readings collected are accurate and accessible.

• Deep Seismic - A deep seismic survey proposed from Lawn Hill across to Croydon will improve the regional understanding of major geological domains and structures between the Mount Isa and Georgetown terrains. The new seismic is proposed to commence in 2025-2026 and will be incorporated into the current deep seismic network to provide a 3-dimensional understanding of the geology across the state.

Action #4 – New Economy Mineral Systems and Geoscience

The Queensland Government invested $5 million in geoscience research on existing copper, cobalt, rare earth, indium and other new economy mineral deposits to better understand their occurrence and distribution. Projects under this banner provide the resources sector with the tools they need to overcome challenges and develop new techniques to aid exploration, discovery, and extraction of minerals. It is increasingly essential as the frontier for discovery moves into deeper and more difficult terrains, while the demand for new economy minerals increases exponentially.

• Geochem Data Update - The updated Queensland Geochemistry Database has an additional 600,000 new data that covers all the 5 Queensland Geochemical data blocks. The new data release is in GDA2020 datum, and are available from Whole of Queensland Geochemistry databases - Whole of Queensland Geochemistry databases - Geochemistry - GSQ Open Data Portal

• Georgetown Hydrogeochem - The Hydrogeochemistry study of eastern Mount Isa has identified seventeen areas of interest for further mineral exploration work. The same technique is applied to the undercover areas surrounding the Georgetown block and fill areas of data gaps in the eastern Mount Isa. All sampling and analytical work have been completed and the various collaborators (GSQ, CSIRO, RUTGERS and QUT) are at the stage of data analysis of the variety of chemistry types, and will integrate them into a final report expected for release in December 2024.

• Characterisation of Queensland mineral deposits - An integrated work program aiming to build up an extensive reference collection of representative drill hole and surface samples and associated geoscience data, to comprehensively characterise geochemical, mineralogical and petrophysical signatures of mineralisation, alteration and distal footprints of key deposits of different deposit types including the north east and north west mineral provinces;

  • GSQ Reference Collection Projects

• Deposit Atlas Phase 3 - Deposit Atlases are a valuable tool for explorers, providing insights to identify the characteristic features and surrounding indicators of major mineral deposits. The third phase of this initiative will examine 28 deposits spanning the Northeast and Northwest Mineral Provinces. Curated by the WH Bryan Mining Geology Research Centre (BRC), each atlas will encompass a detailed report and three-dimensional datasets integrating publicly accessible data.

• Digital Earth - The Digital Earth Project aims to develop a scalable, seamless twin of minerals geoscience data held in the GSQ open data portal. This innovation will visualise, in 3D, regional and local-scale geology, geochemistry, and geophysics, and critically all the Mineral Deposit Atlas data for Queensland. A production-ready version of the app will be assessed for public release from September 2024.

• Isotopes Undercover - Heavier copper isotope signatures in groundwater are indicative of oxidation of copper sulfides during weathering. The 65Cu to 63Cu ratio is used as a potential exploration tool to telescope into potential undercover copper mineralization. A spatial analysis of 42 water

This entry provides access to surficial geology maps that have been published by the Geological survey of Canada. Two series of maps are available: "A Series" maps, published from 1909 to 2010 and "Canadian Geoscience Maps", published since 2010. Three types of CGM-series maps are available: 1)Surficial Geology: based on expert-knowledge full air photo interpretation (may include interpretive satellite imagery, Digital Elevation Models (DEM)), incorporating field data and ground truthing resulting from extensive, systematic fieldwork across the entire map area. Air photo interpretation includes map unit/deposit genesis, texture, thickness, structure, morphology, depositional or erosional environment, ice flow or meltwater direction, age/cross-cutting relationships, landscape evolution and associated geological features, complemented by additional overlay modifiers, points and linear features, selected from over 275 different geological elements in the Surficial Data Model. Wherever possible, legacy data is also added to the map. 2)Reconnaissance Surficial Geology: based on expert-knowledge full air photo interpretation (may include interpretive satellite imagery, DEMs), with limited or no fieldwork. Air photo interpretation includes map unit/deposit genesis, texture, thickness, structure, morphology, depositional or erosional environment, ice flow or meltwater direction, age/cross-cutting relationships, landscape evolution and associated geological features, complemented by additional overlay modifiers, points and linear features, selected from over 275 different geological elements in the Surficial Data Model. Wherever possible, legacy data is also added to the map. 3)Predictive Surficial Geology: derived from one or more methods of remote predictive mapping (RPM) using different satellite imagery, spectral characteristics of vegetation and surface moisture, machine processing, algorithms etc., DEMs, where raster data are converted to vector, with some expert-knowledge air photo interpretation (training areas or post-verification areas), varying degrees of non-systematic fieldwork, and the addition of any legacy data available. Each map is based on a version of the Geological Survey of Canada's Surficial Data Model (https://doi.org/10.4095/315021), thus providing an easily accessible national surficial geological framework and context in a standardized format to all users. "A series" maps were introduced in 1909 and replaced by CGM maps in 2010. The symbols and vocabulary used on those maps was not as standardized as they are in the CGM maps. Some "A series" maps were converted into, or redone, as CGM maps, Both versions are available whenever that is the case. In addition to CGM and "A series" maps, some surficial geology maps are published in the Open File series. Those maps are not displayed in this entry, but can be found and accessed using the NRCan publications website, GEOSCAN:(https://geoscan.nrcan.gc.ca).

Contained within the 4th Edition (1974) of the Atlas of Canada is a map showing geological age and lithology accompanied by a supplementary map at a scale of 1:50 500 000, displaying geological provinces.

Level below which soil or rock is saturated with water, in the well and at the time the level has been measured, expressed in m above the sea level. Groundwater levels measured are interpolated / extrapolated to obtain groundwater level on every cell of the hydrogeological unit raster. Surfer and ArcGis are the software usually used to create groundwater level raster. The dataset designates a raster with a groundwater level, for each cell of the hydrogeological unit.

The NTGS references database has over 9000 geoscience publications and reports such as NWT Open Files/Reports, Mineral Exploration Assessment reports and Theses. This database contains references that are less than 5000 square kilometres and that are spatially referenced (footprints). Exported 2017, Nov.

This publication contains a spatial database of bedrock geological features of the Archean Slavecraton of Northwest Territories and Nunavut. The database was developed by interpretation ofsatellite and aeromagnetic data in conjunction with bedrock maps, from both proprietary andnon-proprietary sources, and has allowed generation of new data and reinterpretation ofgeological relationships. Rock units are classified into a harmonized legend with pan-Slaveapplicability. Point data, including kimberlite locations and geochronological sample sites, forman integral component of the database. The traces of numerous interpreted and mappedfaults, diabase dykes, and topographical lineaments contribute to significant advancements inthe understanding of the Slave’s crustal fracture systems.This compilation builds upon a similar product released by the Northwest Territories GeologicalSurvey (formerly the Northwest Territories Geoscience Office) in 2005 as NWT-NU Open File2005-01. Upgrade, revision, and expansion of geological information primarily by M. Stubley;database design and integrity, and topological consistency by D. Irwin. Both the NorthwestTerritories Geological Survey and the Canada-Nunavut Geoscience Office, the latter throughNRCan, provided financial support to M. Stubley.The compilation was created using ArcMap 10.6.1, and is amenable to integration to other GISplatforms. All data is projected to Universal Transverse Mercator (UTM) Zone 12 North usingNorth American Datum 1983 (NAD83). The accuracy of geological relationships reflects thesource data. Many areas are valid at scales of 1:30,000 to 1:50,000, but more-detailed sourcedata are simplified prior to incorporation.NWT Open File 2019-01 contains information on data sources related to this dataset and additional geological interpretation.Recommended citation: Stubley, M.P. and Irwin, D., 2019.

Slave Craton Geological Compilation: The Slave Craton map (NWT-NU Open File 2005-01) is one of the datasets used to produce the NWT geological bedrock compilation. This dataset represents the compilation of existing geological maps and original geological mapping by NWT geologists. The data were originally compiled in shapefile format and can be output for public distribution in shapefile or PDF format. This map has been modified, and converted into a geodatabase, from the original NWT-NU Open File 2005-01 to fit adjacent provinces fix topology errors and standardize attributes. NWT-NU Open File 2005-01 contains information on data sources related to this dataset and additional geological interpretation.
