Resolving the Late Paleozoic Ice Age in Time and Space
The occurrence of massive, weakly stratified, and stratified diamictites; dropstone
-bearing mudrocks; and sandstones suggests subaqueous ice-proximal
deposition due to various glacio- marine processes (Powell and Domack, 2002).

The Geology of Australia
The glacial deposits have two characteristic rock types: thick beds of tillite, and
dropstone units. The tillite is an unsorted mass of gravel, sand and mud, without
any bedding or stratification, and is the sediment dumped by melting glaciers and
