L199 Yilgarn Craton-Officer Basin-Musgrave (YOM) Magnetotelluric Survey Processed EDI files and support data from sites associated with 11GA-YO1 seismic traverse

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.作为澳大利亚政府2006-2011年陆上能源安全计划的一部分，澳大利亚地质调查局（Geoscience Australia）与西澳大利亚地质调查局合作，沿横穿澳大利亚中西部伊尔冈克拉通（Yilgarn Craton）、奥弗尔盆地（Officer Basin）及马斯格雷夫省（Musgrave Province）的深地壳地震反射测线采集了大地电磁（magnetotelluric, MT）数据。本次大地电磁调查旨在绘制该区域的电阻率分布，并增进对该区域地壳与上地幔结构的科学认知。该数据与深地壳地震反射、地震折射、位场及地质数据所获信息互为补充，共同为该区域的地壳架构与地球动力学研究提供全新认知，对评估该区域的矿产与能源资源潜力具有重要价值。数据集以EDI文件格式提供，并附带辅助说明资料。
