Geoscience Australia’s Exploring for the Future program provides precompetitive information to inform decision-making by government, community and industry on the sustainable development of Australia's mineral, energy and groundwater resources. By gathering, analysing and interpreting new and existing precompetitive geoscience data and knowledge, we are building a national picture of Australia’s geology and resource potential. This leads to a strong economy, resilient society and sustainable environment for the benefit of all Australians. This includes supporting Australia’s transition to net zero emissions, strong, sustainable resources and agriculture sectors, and economic opportunities and social benefits for Australia’s regional and remote communities. The Exploring for the Future program, which commenced in 2016, is an eight year, $225m investment by the Australian Government.

We present a 3-D resistivity model derived from magnetotelluric data collected by two recent surveys in the Curnamona and Delamerian Region: the Curnamona Cube survey led by the University of Adelaide and funded by AuScope and the Curnamona Cube Extension survey (https://doi.org/10.26186/147904) by Geoscience Australia as part of Exploring for the Future Program. In total, data from 231 sites were used to produce 3-D models using the ModEM code. Details of data inversion are provided in the Readme.pdf file. The resistivity model can be used to enhance the understanding of the geodynamics and mineral potential in the Curnamona Province and Delamerian Orogen.

We greatly appreciate that Prof. Graham Heinson from the University of Adelaide has made the Curnamona Cube survey data available for this work. The modelling work was undertaken with the assistance of resources from the National Computational Infrastructure (NCI Australia).

This release package contains the preferred 3-D resistivity model in SGrid format and geo-referenced depth slices in .tif format.
