Evidence for glacial erosion of competent intrusive igneous rock is described for sites at Quart Pot Creek, Stanthorpe, Queensland. The bedrock, comprising the Stanthorpe Adamellite, was emplaced during the Early-Middle Triassic. It is argued that the pluton was exposed during the late Middle - Late Triassic and subjected to glacial erosion at that time. This was consequent to the rapid uplift and denudation of the landscape, which accompanied the Hunter-Bowen Orogeny. Burial of the eroded surface occurred most probably during that ice age and a subsequent period of subsidence. The ancient surface has been exhumed during more recent denudation. It is suggested that during the late Middle - Late Triassic, climatic conditions remained cold enough over this part of southeastern Australia at least for valley glaciers to form and influence landscape development. |
