News from the surveys: SA

摘要

The Geophysics and Prospectivity (GAP) Team in the Geological Survey of South Australia (GSSA) have been busy over the past few months working on a range of projects. This article gives a brief overview into some of these projects. Much of the team's effort has been dedicated to capture and processing of geophysics in the Woomera Prohibited Area (WPA). The WPA is a military test and evaluation site of approximately 127000 km~2 (approximately 13% of the State) in the north-west region of South Australia. It also covers over 30% of the Gawler Craton - some of the most prospective ground in South Australia (copper, gold, uranium and iron ore). Agreements have been reached to allow exploration in the area and the GSSA has funded a large-scale gravity survey covering a major portion of the WPA. DaishSat Geodetic Surveyors undertook the survey between May and September 2013 and at the time of writing the data is undergoing final QA/QC, prior to an expected public release in December. The GSSA will be preparing new gravity imagery for the region, as well as updated magnetic grids.
