"The ‘1:2 500 000 major crustal boundaries of Western Australia, 2021’ digital layer is a regional compilation of interpreted crustal boundaries that penetrate the lithosphere or bound tectonic units at the terrane or province scale. These boundaries have been interpreted and extrapolated from a variety of geological and geophysical datasets, primarily seismic reflection profiles, outcrop geology, and potential field data (gravity and aeromagnetics). Tectonic events ascribed to each boundary are defined in the GSWA Explanatory Notes Database (February 2021). The positional accuracy of these boundaries is low, due primarily to their crustal scale and uncertainties in interpreting the primary data sources, and consequently this map is best used at the nominal scale or smaller.
