From: The antiquity of Nullarbor speleothems and implications for karst palaeoclimate archives
Pliocene cavescapes. The interior of a typical, well-decorated Nullarbor cave. None of these formations are active at the present day and our U-Pb dating program suggests that most of the speleothems are Pliocene in age: these are, in effect, fossil landscapes, frozen in time. These materials, and others like them from around the globe, form a remarkable but largely unrecognized archive of palaeoclimatic and palaeoenvironmental information.
