Resistivity model of the southeast Australian mainland from AusLAMP magnetotelluric data

The Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) aims to collect long period magnetotelluric data on a half degree (~55 km) grid across the Australian continent. New data have recently been collected in New South Wales under a National Collaborative Framework agreement between Geoscience Australia and the Geological Survey of New South Wales.This data release contains a preferred resistivity model and associated inversion files for southeast Australia using data from AusLAMP Victoria (Duan & Kyi, 2018), far west NSW (Robertson et al. 2016) and from the rest of New South Wales up to August 2019 (Kyi et al 2020). The original work behind this model can be cited through the following paper which contains discussion on model development and its significance for tectonic evolution and metallogenic potential:Kirkby, A., Musgrave, R.J., Czarnota, K., Doublier, M.P., Duan, J., Cayley, R.A., Kyi, D., 2020.

澳大利亚岩石圈结构大地电磁计划（Australian Lithospheric Architecture Magnetotelluric Project, AusLAMP）旨在澳大利亚大陆全域范围内，以半度（约55公里）的网格布设方案采集长周期大地电磁（long period magnetotelluric）数据。近期，依托澳大利亚地质调查局与新南威尔士州地质调查局签署的国家合作框架协议，研究团队在新南威尔士州完成了新增大地电磁数据的采集工作。本次发布的数据包含澳大利亚东南部的优选电阻率模型及配套反演文件，所用数据源自AusLAMP维多利亚州数据集（Duan & Kyi, 2018）、新南威尔士州远西部地区数据集（Robertson et al. 2016），以及截至2019年8月的新南威尔士州其余区域数据集（Kyi et al 2020）。该模型的原创研究可通过以下论文进行引用，该论文探讨了模型构建过程及其对于构造演化与成矿潜力的研究意义：Kirkby, A., Musgrave, R.J., Czarnota, K., Doublier, M.P., Duan, J., Cayley, R.A., Kyi, D., 2020. 基于大地电磁数据的显生宙造山带岩石圈结构：澳大利亚东南部塔斯曼造山带中的AusLAMP项目. 《构造物理学报（Tectonophysics）》，第793卷，文章编号228560。
