Magnetotelluric surveys are playing an increasing role in Australian geoscience, including academic research, data collected by geological surveys (including a role in Geoscience Australia's $58.9 million Onshore Energy and Security Program), mineral exploration and geothermal exploration. This project will enable the results of these surveys to be interpreted more accurately and meaningfully by constraining the expected resistivities of crustal rocks at various pressures and temperatures. This research is vital if the investment currently being put into MT surveys is to be capitalized upon.

大地电磁测量在澳大利亚地球科学中发挥着越来越重要的作用，包括学术研究、地质调查收集的数据（包括在澳大利亚地球科学的5890万美元陆上能源和安全计划中所起的作用）、矿产勘探和地热勘探。该项目将通过限制不同压力和温度下地壳岩石的预期电阻率，使这些调查结果能够更准确和更有意义地解释。如果要将目前投入MT调查的投资资本化，这项研究是至关重要的。
