The WACHEM database is a compilation of multi-element geochemistry of rocks unconsolidated surface material (regolith) and drill core collected by the Geological Survey of Western Australia. Samples have been analysed for a range of major element oxides, trace elements, rare earth elements (REE), and isotopes by a variety of analytical approaches at commercial, government and university laboratories. In most cases, analysis of unknowns has been carried out along with samples of know composition (reference materials), a second sample of the unknown (sample duplicate), and material which does not contain detectable amounts of elements of interest (blank). These data are included with analysis of unknowns, and these quality control data can be used to gauge the quality of analysis. For inclusion in the geochemical database, analytical data for each element in each sample must include the unit of measurement, lower level of detection (LLD) of that element, and an indication of the analytical technique (usually specified as a laboratory-specific code). To minimise the inclusion of spurious data in the database, analytical batch data are loaded with reference to a set of look up tables, against which data can be checked for consistency.

This is the spatial data for the EXACT (EXploration ACTivity) database. The EXACT database contains information on exploration activities described in open file mineral exploration reports (WAMEX online) for specific project areas that were studied for their mineral prospectivity by Geological Survey of WA geologists. The project areas were Arunta - Musgrave, Bangemall Basin, Canning, Earaheedy, East Kimberley, East Pilbara, Gascoyne, Mid West coast, North Eastern Goldfields, North Kimberley, North Murchison, Paterson, Peak Hill, South West, West Hamersley, West Kimberley, West Pilbara. The highest A No in the database is A69999. The final update was in 2009 when work on it was terminated.

The Mineral Deposits and Mineral Resources OGC service provides data from Geoscience Australia’s OZMIN database in EarthResourceML 2.0 and ERML Lite 1.0 and associated contextual layers in simple WMS and WFS formats.

Analytical results and associated sample and analysis metadata from the analysis of minerals in earth material samples.
