b'Geophysics in the surveysNewsGeological Survey of Western Australia: Western O\x1bcer and Perth Basins SEEBASE reportsIn 2005, Frogtech Geoscience completed the Structurally Enhanced View of Economic BASEment (OZSEEBASE) project, which resulted in a continental-scale depth-to-basement grid highlighting the Phanerozoic basins across Australia. With the acquisition, since then, of many new potential \x1deld, seismic and well datasets, as well as more recent Geological Survey of Western Australia (GSWA) seismic interpretation, GSWA contracted Geognostics Australia Pty Ltd to revise the SEEBASE model of the western O\x1bcer Basin (within the State jurisdiction) and the Perth Basin, which also includes o\x1eshore areas in Commonwealth Waters.The two SEEBASE projects have markedly increased the resolution of the depth-to-basement model compared to the 2005 version, and have improved identi\x1dcation of major structures, basement faults, crustal architecture and basement composition (Figures 1 and 2). These new products were funded by the State Governments Exploration Incentive Scheme (EIS) andFigure 1.Depth-to-basement map of 2022 SEEBASE project of the western O\x1ccer Basin, superimposed on form a valuable pre-competitive datasetthe digital elevation model.for both the minerals and energy industries.How to access the reportsReport 235 western Officer Basin SEEBASE structural study and GIS, and Report 236 Perth Basin SEEBASE structural study and GIS are available on the Department of Mines, Industry Regulation and Safety eBookshop https://www.dmp.wa.gov.au/ebookshop. The digital layers and ArcMap projects are available as USB packages and can be ordered from the same location. Digital layers include the various interpreted basement-related layers and processed and filtered magnetic and gravity datasets. The interpreted basement layers can also be viewed in the Energy Systems Atlas, an online interactive map viewer available via Western Australian Petroleum and geothermal Information Management System (WAPIMS) at https://wapims.dmp.wa.gov.au/wapims.Deidre Brooks Geological Survey of Western AustraliaFigure 2.The depth-to-basement, Bouguer gravity anomaly and reduced-to-pole magnetic images from deidre.brooks@dmirs.wa.gov.au the 2022 Perth Basin SEEBASE project (left to right).21 PREVIEW JUNE 2023'
