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.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.This data release includes acquired time series data, metadata, and processed data for each site. The script used to package the time series data is also provided. The time series data are available in their original format (.txt), as recorded by the data logger, as well as in MTH5 hierarchical format. The open-source MTH5 Python package (https://github.com/kujaku11/mth5) was used to convert the recorded data to MTH5 format. Processed data are provided in Electrical Data Interchange (EDI) format. Time series data is available on request from [e-mail] - quote eCat#150000. 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.
