Discovery Trails: virtual geology
Step through and discover South Australia’s geology.
We’re excited to introduce our newest feature in SARIG: Discovery Trails, the ability to view virtual tours of South Australia’s geology from your desktop computer or mobile device.
Discovery Trails highlight real locations across the state and combine multimedia elements such as images, text and videos to showcase our diverse geological history.
The first Discovery Trail, Rocks of the southern margin of the Gawler Ranges, features a rock sample field trip along the southern margin of the Gawler Range Volcanic Province (Fig. 1).

Southern margin of the Gawler Ranges
The Geological Survey of South Australia, in collaboration with the Deep Exploration Technologies Cooperative Research Centre (DET CRC), Minotaur Exploration and Kingston Resources, carried out a Mineral Systems Drilling Program (MSDP) along the southern margin of the Gawler Ranges between July 2015 and April 2016. Working alongside the MSDP, a detailed geological mapping program was carried out to provide a regional geological context to assist with stratigraphic interpretation and assessment of the mineral potential of the region. The mapping program comprised detailed basement, structural and regolith mapping, as well as petrological, whole rock geochemical, isotopic and geochronological studies.
The Discovery Trail features nearly 100 rock samples collected during this program, spanning basement through to cover, with the main focus on the Mesoproterozoic Gawler Range Volcanics and Hiltaba Suite. The majority of the samples were collected in each of the three MSDP drilling areas along the southern margin of the Gawler Ranges, including the Six Mile Hill, Peltabinna and Mount Double 1:75,000 geological map sheets.
