Glacial sediments and cap carbonate sequences in the Umberatana Group: Evidence for a snowball Earth?

Bridget Ayling
Abstract: 

The Umberatana Group brackets two of the largest glaciations in Earth's history - the Sturtian and Marinoan glaciations. In the central Flinders Ranges, several interesting aspects of the Umberatana Group are exposed, particularly in the vicinity of the Enorama Diapir. Here continued movement of the diapir after the group was deposited has resulted in exposure of the complete group within a relatively small area (see Figure 1).
