GSWA petrophysics update: insights from physical property cross plots

GSWA commenced a five-year petrophysical sampling program in 2021. The data collected as part of this program will enable more informed decision making for the resources exploration industry, government agencies and solid Earth science research in WA. To date, 171 publicly available drillcores have been petrophysically sampled from across WA. We present this data and complete a first-pass regional-scale analysis of the magnetic susceptibility, galvanic resistivity, dry bulk density, chargeability, pwave velocity, and apparent porosity for a variety of rock types. This first pass analysis compared different rock types from different regions, however, further interrogation of the data on a more local scale will improve our understanding of the physical property trends for different alteration assemblages, mineralisation styles, and lithologies for different geographical regions. All petrophysical data results are published to GSWA's MAGIX platform and can be downloaded by searching for the petrophysics method.
