The primary 1:2 500 000 State interpreted bedrock geology (DMIRS-014) is one of four digital data layers that make up the 1:2 500 000 geological map of Western Australia. The other three are the 1:2 500 000 State Cenozoic geology, the 1:2 500 000 State interpreted dyke suites, and the 1:2 500 000 State interpreted bedrock geology structural lines (DMIRS-013). The 1:2 500 000 interpreted geology contains geoscience data covering themes such as geology and tectonic boundaries that have been digitally rolled up from 1:500 000 data sources for optimal display at 1:2 500 000 scale. The Cenozoic geology layer can be superimposed over the bedrock layer to allow the interpreted extension of older bedrock geology under Cenozoic cover, where geological and geophysical information permits, and to depict Cenozoic paleovalleys and additional significant Cenozoic cover. The nomenclature and hierarchy of lithostratigraphic units is based on the GSWA Explanatory Notes System (extracted September 2015). Stratigraphic units are mostly displayed at greater than or equal to Group or Suite level; Subgroups and Formations are only displayed where areal extent warrants it and the unit does not have a higher order parent. The data are held in GDA94 decimal degrees. This dataset was formally known as 1:2 500 000 State interpreted bedrock geology (DMP-011)
