GSWA rock classification scheme
Listing of rock types and lithological nomenclature (and related codes) used by the Geological Survey of Western Australia (GSWA) for the dual purpose of recording lithologies during mapping / core logging, and for representing mappable lithostratigraphic/lithotectonic units in the State. Rather than attempting to cover for all existing rock types and lithologies, the GSWA’s scheme and terms in this vocabulary are specifically informed by Western Australian geology; a companion vocabulary covers lithological equivalents for regolith materials.
