The dataset is made publicly available as a GIS at nominal 1:5 000 000 scale, and shows the time-space-event distribution of mafic-ultramafic magmatism in Australia from the early Archean to the present day. Development of this GIS has been a multi-year project and earlier released extracts (in viewable pdf form with accompanying Geoscience Australia Records) included compilations for the Archean magmatic record, the Proterozoic magmatic record, and the Australian Large Igneous Provinces (LIPs). Publication of the GIS completes the series with addition of the Phanerozoic magmatic record, and formalisation of the complete record of Archean-Phanerozoic magmatic events as a single series. The chronology of Australian mafic-ultramafic magmatism resolves into 74 magmatic events within, predominately, resolvable bands of ±10 million years. Each event is identified by geological units grouped by similar age - this coeval magmatism may or may not be genetically related and may be in response to different geodynamic environments. These magmatic events range in age from the Eoarchean ~3730 Ma ME 1 - Manfred Event, confined within a small remnant domain within the Yilgarn Craton, to the widespread record of Cenozoic magmatism in eastern Australia (ME 72 to ME 74). The magmatic events range in magnitude from the giant volumes of magma in Large Igneous Provinces, to events whose only known occurrence is an isolated record of dated mafic igneous rock in a single drillhole. The GIS makes it possible to focus on the location of any one of these magmatic events, or groups of magmatic events that may be of interest, and overlay context from any other information that users may have available. The delineation of magmatic events for this study is based on several hundred published ages of mafic and ultramafic igneous rocks from different isotopic systems and minerals. In addition to their ages and extents, primary recorded aspects of each magmatic event include the presence or absence of ultramafic components. Further to this, the presence or correlation of known magmatic-related mineralisation is highlighted in Time-Space-Event Charts of Australia (Appendix D, figures D1 and D2). The basis for mapping has been regional solid geology, interpreted basement geology and surface geology base maps made available by the State and Northern Territory geological surveys, providing insight into the total areal extent of the magmatic systems under cover. Also available to complement the Event GIS are the domains and element boundaries from the Australian Crustal Elements map. These boundaries which are which are based on geophysical extrapolation of crustal elements under the cover of continental basins, provide a framework of the shallow crustal structure of the continent, and are used in this guide. The Crustal Elements digital dataset is available for download from the Geoscience Australia website. Insight into the geodynamic development of the continent is provided by the magmatic event structure through time. The compilation draws attention to concentrations of mafic-ultramafic magmatism in the Archean from ~2820-2665 Ma, in the Proterozoic from ~1870-1590 Ma, and in the late Neoproterozoic-Phanerozoic from ~530-225 Ma. These three time spans contain 39 of the 74 magmatic events, 53% of the entire mafic-ultramafic magmatic event record of the continent. The periods in between have mafic-ultramafic magmatic records that are more dispersed in time. Other features of interest include the shared geographic and crustal element locations of Large Igneous Provinces and numerous events with smaller magma volumes.

The land-use profile surrounding a neighbourhood is a determinant of health and associated with socioeconomic outcomes. In Australia, there is no national publicly available dataset detailing the land-use profile surrounding residential neighbourhoods. Using PostGIS a centroid was placed in every Australian Bureau of Statistics (ABS) defined Mesh Block (MB) – the smallest geographical structure in Australian geography which details the category of land-use (i.e. residential, parkland, commercial, industrial etc.) and population. Each MB was assigned a remoteness classification and socioeconomic status, as defined by the ABS. After a buffer based on a radius of 400 metres, 1-kilometre, 2-kilometres, and 5-kilometres was calculated around each centroid, the square metre of, and the percentage of the buffer covered by, each land-use category was calculated. This dataset will support the decisions of urban planners, diverse government departments, researchers and those involved in public and environmental health.

The Australian Proterozoic Large Igneous Provinces GIS Dataset is designed for display at a nominal 1:5 000 000 scale, showing the time-space distribution of Proterozoic Large Igneous Provinces (LIPs) in Australia. Large Igneous Provinces are relatively rare magmatic events distinguished by exceptionally large volumes of mafic dominated magma emplaced over short geological periods of a few millions years or less. Five major LIPs have been recognised, or proposed, so far in Australia, beginning with the ~1780 Ma Hart LIP, followed by the ~1210 Ma Marnda Moorn LIP, the ~1070 Ma Warakurna LIP, the ~825 Ma Gairdner LIP, and the ~510 Ma Kalkarindji LIP. The early Cambrian Kalkarindji LIP is included in this Proterozoic compilation because of its size and importance. Only the youngest two of these LIPs (Gairdner and Kalkarindji) are established as comagmatic provinces based on both time correlation and geochemical equivalence. The other proposed LIPs (Hart, Marnda Moorn and Warakurna) are based on time equivalence alone. For further information on the five proposed Proterozoic LIPs refer to the guide to using the map of Australian Proterozoic Large Igneous Provinces (Geoscience Australia Record 2009/44).

Earlier released extracts include two pdf maps of Australian Proterozoic Large Igneous Provinces and an accompanying Geoscience Australia Record. This release presents the Australian Proterozoic Large Igneous Provinces as a GIS dataset and it should be used in conjunction with the Australian Mafic Ultramafic Magmatic Events GIS Dataset released by Geoscience Australia in 2014 (link). This file geodatabase that contains points, lines and polygons representing mafic and ultramafic rocks in Australia which have been placed in a magmatic event framework in time and space, primarily based on geochronological data. Together, these datasets provide comprehensive information on the evolution of mafic-ultramafic magmatism associated with the Australian continent, and will be of interest to explorers in the search of magmatic ore deposits of nickel, platinum-group elements, chromium, titanium, and vanadium.
