This compilation of written and associated oral papers that were presented for the “What lies beneath the western Gawler Craton? 13GA-EG1E Seismic and Magnetotelluric Workshop 2015” is an important step in building our geological understanding of one of the greatest geological frontiers on the Australian continent. Little is yet known about the bedrock geology underlying the Nullarbor Plain and its eastern margins, largely because deep drill hole sections and samples are sparse across the region, but also because, in parts such as the far west of South Australia, the regional geophysical coverage has only been derived to date from early-run programmes having widely spaced points of data acquisition. However, the likely wealth of geological knowledge to be gained from this region is vital not only for better understanding the geological evolution of South Australia, but to inform a large part of the conceptual geological reconstruction of the Australian continent. This publication marks some of the first steps in addressing this lack of data and knowledge, and it thereby provides critical foundations for obtaining new scientific insights and understanding of our country.

Notes: During December 2013 and January 2014, 834 line km of 150 fold deep seismic reflection data were acquired along a single Vibroseis traverse that began at Haig, WA and was continued east along a service road/track running parallel to the Trans Australian Railway, to end at Tarcoola, SA. The traverse spanned parts of the Eucla Basin and the western Gawler Craton. For most of the survey's coverage, the seismic data obtained provide images of the full vertical extent of the crust underlying these two regions, to ~ 60 km depth. The processed seismic data, and especially those reflections obtained from the upper 25 km of the crust, are considered to have provided valuable information about the nature of major crustal structures, igneous intrusions and basinal sedimentary layering, and preliminary interpretations of their geological significance are the subject of this workshop, which was conducted at the Geological Survey of South Australia on 10/12/2015 in the lead-up to the 12th South Australian Exploration and Mining Conference held at the Adelaide Convention Centre on 11/12/2015.
