Abstract
Abstract for 2015 Conference of the Specialist Group of Tectonics and Structural Geology. Presentation of 3D Models in the Grampians-Stavely Zone, western Victoria. 3D geological models have been produced for two major geological units in the Grampians-Stavely Structural Zone in western Victoria. The Grampians-Stavely Zone is located on the eastern limit of the Cambrian-aged Delamerian Orogen in Victoria (VandenBerg et al., 2000; Crawford et al., 2003; Miller et al., 2005) and several belts of Cambrian igneous rocks with arc affinities have been recognised within this zone (Crawford and Keays, 1978; Buckland, 1987; VandenBerg et al., 2000; Crawford et al., 2003); including the exposed Mount Stavely Volcanic Complex (Buckland, 1987). The Mount Stavely Volcanic Complex, together with other belts of Cambrian igneous rocks, have been interpreted as fault slices of a now mostly buried magmatic arc system referred to as the Stavely Arc (Schofield et al., 2015; Cayley et al., in prep.). In order to address the outstanding geological questions and challenges to exploration in the Grampians-Stavely Zone, Geoscience Australia and the Geological Survey of Victoria established the collaborative Stavely Project in 2013. The Stavely Project forms part of the broader UNCOVER initiative (Australian Academy of Science, 2012) and aims to provide the fundamental framework for discovery in the Grampians-Stavely Zone. This is done using a mineral systems-based approach (Wyborn et al., 1994) through the provision of pre-competitive geoscientific data. This approach involves characterising the subsurface geology, recognising favourable geological environments for the formation of major mineral systems, identifying important elements that demonstrate mineral systems potential, and understanding the depth and nature of cover across the region. This study will focus on understanding the depth and nature of specific cover units across the region.
