This OGC compliant service provides access to magnetotelluric data and associated products, which have been produced by Geoscience Australia’s Magnetotelluric Program. This program includes regional magnetotelluric projects and the Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP), a collaborative project between Geoscience Australia, the State and Northern Territory geological surveys, universities, and other research organisations. The data provided in this service comprise resistivity model depth sections and the locations of sites used in these studies.

The Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) is a collaborative national survey that acquires long-period magnetotelluric data on a half-degree grid spacing (approximately 55 km) across the Australian continent. This project aims to map the electrical conductivity/resistivity structure in the crust and mantle beneath the Australian continent. Geoscience Australia has a significant investment in AusLAMP and is a key contributor to the delivery of this national program. Geoscience Australia, in partnership with State and Northern Territory Geological Surveys, has also undertaken regional-scale MT surveys, along onshore deep reflection seismic transects and in potential mineral and energy provinces across the country. The targeting signal range is 10 KHz – 1000 s, which provide an investigation depth from tens of metres to tens of kilometres. These data provide new insights into basement architecture and resource potential in these regions. We will present some new models and results from AusLAMP data and regional survey data, showing a remarkable correlation between conductive anomalies, crustal-scale boundaries and the distribution of giant mineral deposits. For example, the Carpentaria Conductivity Anomaly at the eastern margin of the Mount Isa Province characterises the position and geometry of the ancient Gidyea Suture Zone. The distribution of known gold and copper deposits shows a close spatial correlation with the suture zone, indicating that this structure is potentially a fundamental control on IOCG deposits in its vicinity. The implication is that crustal-penetrating structures act as potential pathways for fluid movement to form mineral deposits in the upper crust.
