Geochemical Classification of Mafic to Ultramafic rocks in Australia GIS Dataset

Mafic and ultramafic analytical samples, derived from Geoscience Australia's corporate Oracle OZCHEM Whole Rock Geochemistry Database, are assigned an igneous rock classification, e.g., tholeiitic, alkaline, based on their lithological and unit descriptions and their analysed geochemical data. This first-pass classification was undertaken to provide an additional tool to assist with metallogenic interrogation of the data. The mafic and ultramafic analytical samples are also assigned, where possible, a geological event based on their relationship to the Australian Mafic-Ultramafic Magmatic Events GIS Dataset. The GeochemicalClassification table is designed to be used in conjunction with Geoscience Australia's Corporate Oracle OZCHEM Whole Rock Geochemistry Database (http://www.ga.gov.au/metadata-gateway/metadata/record/gcat_a05f7892-d0ec-7506-e044-00144fdd4fa6/OZCHEM+National+Whole+Rock+Geochemistry+Dataset) and the Australian Mafic-Ultramafic Magmatic Events GIS Dataset (http://dx.doi.org/10.4225/25/54125552CDA7C).
