Brief description
As part of the Australian Government's Onshore Energy Security Program (2006-2011) Geoscience Australia in collaboration with Geological Survey of Western Australia acquired magnetotelluric (MT) data along the deep crustal seismic reflection transect across the Yilgarn Craton, Officer Basin and Musgrave Province in Central Western Australia. The aim of the MT survey is to map the electrical resistivity distribution and improve scientific understanding of the crustal and upper mantle structure in this region. This information is complementary to that obtained from deep crustal seismic reflection, seismic refraction, potential field and geological data, which together provide new knowledge of the crustal architecture and geodynamics of the region. It is important for helping to determine the potential for both mineral and energy resources. Data are supplied as EDI files with support information.Lineage

Statement: These data were acquired using Bartington Mag-03MS Fluxgate magnetometer for long-period measurements and LEMI-120 Induction Coil Induction coil magnetometers for broadband measurements. Data were recorded on PR 6-24 Portable Earth Data recorders with GPS timing synchronisation. This equipment was supplied by AuScope.
Data was processed in Geoscience Australia to Electrical Data Interchange (EDI) files.
