Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) - Queensland phase three data release

The Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) is a collaborative national survey that acquires long-period magnetotelluric (MT) data on a half-degree grid spacing across Australia. This national scale survey aims to map the electrical conductivity/resistivity structure in the crust and upper mantle beneath the Australian continent, which provides significant additional information about Australia’s lithospheric architecture and geodynamic framework as well as valuable pre-competitive data for resource exploration.<br>Geoscience Australia (GA) in collaboration with the Geological Survey of Queensland acquired AusLAMP data in Queensland from May 2023 to July 2024. The funding of the survey was provided as part of the Queensland Government's Queensland Resource Industry Development Plan. The data were acquired using GA's LEMI-424 instruments and were processed using the Lemigraph software. The processed data contain transfer functions for each site in Electrical Data Interchange (EDI) format. <br>This data release includes site locations, processed data in EDI format, and time series data in the format of the LEMI-424 data logger and a hierarchical data format MTH5 (Peacock. J, et al. 2022, https://doi.org/10.1016/j.cageo.2022.105102). Time series data is available on request from [e-mail] - quote eCat#150000.<br>We acknowledge the traditional landowners, private landholders and national park authorities within the survey region, without whose cooperation these data could not have been collected. <br>

澳大利亚岩石圈构造大地电磁计划（Australian Lithospheric Architecture Magnetotelluric Project, AusLAMP）是一项国家级合作调查项目，在澳大利亚全境以半度网格间距采集长周期大地电磁（magnetotelluric, MT）数据。这项全国性尺度的调查旨在刻画澳大利亚大陆下方地壳与上地幔的电导率/电阻率结构，可为研究澳大利亚岩石圈构造与地球动力学框架提供关键补充信息，同时为资源勘探提供极具价值的预竞争性数据。
澳大利亚地球科学局（Geoscience Australia, GA）与昆士兰州地质调查局合作，于2023年5月至2024年7月在昆士兰州开展了AusLAMP数据采集工作。本项目的资助资金来自昆士兰州政府《昆士兰州资源产业发展计划》。数据采集使用GA的LEMI-424仪器完成，并通过Lemigraph软件进行处理。经处理的数据包含各测点的传递函数，格式为电子数据交换（Electrical Data Interchange, EDI）格式。
本次发布的数据包含测点位置信息、EDI格式的处理后数据，以及LEMI-424数据记录仪格式的时序数据与层级化数据格式MTH5（Peacock J等, 2022, https://doi.org/10.1016/j.cageo.2022.105102）。时序数据需通过邮箱[e-mail]申请获取，并请在申请时引用eCat编号150000。
我们谨向调查区域内的传统土地所有者、私人土地持有者与国家公园管理方致谢，若无他们的协助，本数据采集工作将无法顺利完成。
