 "abstract": "A broadband magnetotelluric transect across the central Delamerian Orogen, South Australia, acquired by the Geological Survey of South Australia with the University of Adelaide in September and October 2020. The survey occupied 63 stations along a 100 km profile trending southeast from Manna Hill, recorded on LEMI-423 systems drawn mostly from the AuScope instrument pool supplementing the GSSA's own LEMI fleet. The profile crosses the transition from the eastern hinge of the Nackara Arc into the Loch Lily Kars Belt, where the rocks lie concealed beneath Murray Basin sediments. This package carries 53 released EDI transfer function files from the 63 occupied stations, spanning periods of 0.005 s to 4000 s.",
