The Dawson Hill Member of the Grindstone Range Sandstone in the Flinders Ranges, South Australia

Abstract The Dawson Hill Member of the Grindstone Range Sandstone is the uppermost unit of the Lake Frome Group, and the highest exposed unit in the Neoproterozoic to Cambrian sedimentary succession in the Flinders Ranges, South Australia. It is formally defined herein from a 190m thick type section that has no exposed top. The Dawson Hill Member comprises mainly poorly sorted, cross-bedded sandstone which, at some levels, contains abundant well rounded pebbles and cobbles of quartzite and quartz derived from an unknown source area to the southwest in the early stages of the Delamerian Orogeny. The age of the unit is poorly constrained. It is probably of late early Cambrian or early middle Cambrian age.
