 "abstract": "Magnetotelluric survey of the Olympic Domain, Gawler Craton, South Australia. 341 transfer functions over 333 sites were acquired between 23 March and 28 June 2018 by Zonge Engineering and Research Organisation (Australia) on behalf of the Geological Survey of South Australia and Geoscience Australia under the GSSA PACE Copper initiative, and reprocessed by CGG Geoscience in July 2019; six stations at Maslin were collected and funded by Investigator Resources Ltd and provided by the GSSA. The survey is released open-file through SARIG record mesac2170, survey envelope 2018SA005, and held by Geoscience Australia as eCat 126345. AusMT serves all 341, each carrying impedance and tipper with variances across 67 to 104 frequencies, reaching 10.4 kHz at 209 stations and a median longest period of 2330 s. The package is assembled per station from the custodian's three overlapping copies; those choices, the three contractor layout corrections and the instrument caveat are documented in README.md.",
