<div>The Proterozoic alkaline and related igneous rocks of Australia is a surface geology compilation of alkaline and related igneous rocks of Proterozoic age in Australia. This dataset is one of five datasets, with compilations for Archean, Paleozoic, Mesozoic and Cenozoic alkaline and related igneous rocks already released.</div><div><br></div><div>Geological units are represented as polygon and point geometries and, are attributed with information that includes, but is not limited to, stratigraphic nomenclature and hierarchy, age, lithology, composition, proportion of alkaline rocks, body morphology, unit expression, emplacement type, presence of mantle xenoliths and diamonds, and primary data source. Source data for the geological unit polygons provided in Data Quality LINEAGE. Geological units are grouped into informal geographic “alkaline provinces”, which are represented as polygon geometries, and attributed with information similar to that provided for the geological units.</div>

This web service delivers datasets produced by the Critical Minerals Mapping Initiative (CMMI), a collaboration between Geoscience Australia (GA), the Geological Survey of Canada (GSC) and the United States Geological Survey (USGS). Data in this service includes geochemical analyses of over 7000 samples collected from or near mineral deposits from 60 countries, and mineral prospectivity models for clastic-dominated (Zn, Pb) and Mississippi Valley-type (Zn-Pb) deposits across Canada, the United States, and Australia.

This collection supports the compilation of national mineral resource and production statistics, and mineral prospectivity analysis. The collection includes the location of Australian mineral occurrences and mineral deposit descriptions, with geological, resource and production data. This information is stored in two Geoscience Australia databases, the Mineral Deposits & Occurrences Database (OZMIN) and the Mineral Occurrence Locations (MINLOC) database. The collection also includes a number of supporting Geographic Information System (GIS) datasets (e.g., mineral prospectivity datasets, ports, power stations); maps and reports. <b>Value:</b> Data related to the known location and production of mineral resources supports decisions related to resource and economic development. <b>Scope: </b>The collection covers the Australian continent and is updated annually. It now contains data on over one thousand major and historically significant mineral deposits for 60 mineral commodities (including coal).
