Rethinking eastern Australian caves
Abstract:

There are some 300 bodies of cavernous limestone in eastern Australia, extending from Precipitous Bluff in southeastern Tasmania to the Mitchell Palmer region in north Queensland. These impounded karsts, developed in Palaeozoic limestones of the Tasman Fold Belt System, contain many caves. The caves have a suite of features in common that allows them to be thought of as a major group: the Tasmanic Caves. The Tasmanic Caves include multiphase hypogene caves such as Cathedral Cave at Wellington and multiphase, multiprocess caves such as Jenolan with Carboniferous hypogene and younger paragenetic and fluvial elements. Active hypogene caves occur at Wee Jasper and possibly at five other localities. The Tasmanic Caves are one of the most complex suites of caves in folded Palaeozoic limestones in the world. Field techniques developed to study these caves are now being applied to complex caves in central Europe: in the Czech Republic, Hungary, Poland, Slovakia and Slovenia.
