50-Million-Year-Long Record of Glacial to Postglacial Marine Environments Preserved in a Carboniferous–Lower Permian Graben, Northern Perth Basin, Western Australia

The Perth Basin is an intracratonic rift in Western Australia and contains a Carboniferous to Cretaceous infill in excess of 12 km thick. Some 2 km of mid-Carboniferous to Lower Permian glacially influenced marine strata spanning the Serpukhovian to Kungurian (about 50 My), form one of the longest late Paleozoic cold-climate successions preserved anywhere in Gondwana and record the transition from full glacial to postglacial conditions at high …
