Abstract

Uranium-thorium dating of speleothems from two caves in the Junee-Florentine karst, Tasmania, provides some age constraints for associated clastic sediments including coarse dolerite-rich fluvial gravels, which underlie the three oldest dated speleothems. The results suggest minimum ages of 15 ± 5 ka, ~325 ka and >350 ka (two dates) for the gravels, implying that they are considerably older than the early Last Glacial age suggested previously for some fluvial gravels in other Junee-Florentine caves.
