Abstract
<div>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.</div><div><br></div><div>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. </div><div><br></div><div>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.
