 "abstract": "Audio-magnetotelluric survey of the Carrapateena, Etesian and Khamsin prospects, Gawler Craton, South Australia, acquired for OZ Minerals by Zonge Engineering and Research Organization between 25 October and 8 November 2018 (Zonge job 180165) and later released open-file by the Geological Survey of South Australia. One hundred and thirty stations at roughly 200 to 400 m spacing across three target areas. Five-channel recordings of at least two hours covered 10 kHz down toward 0.1 to 0.01 Hz, using Phoenix MTU-5A receivers with MTC-150L coils and 100 m electric dipoles, remote-referenced to a dedicated site. A 4 degree magnetic declination was applied in processing, so the tensors are referenced to true north. Measured across the 130 files as served: every station tops out at 10.4 kHz and reaches a longest period of 220 s to 4401 s (median 1554 s), 129 of the 130 are remote-referenced with CAR-3 the one single-site solution, and recording durations run 1.9 h to 21.9 h (median 9.0 h).",
