What maps are needed now?
A panel discussion was held during the Sixth BMR Symposium in Canberra in May 1977, on what earth-science maps are needed now in Australia. This account gives background... -
A new lithostratigraphic framework for the Early Jurassic units in the...
Recent detailed studies of key transects throughout the Clarence-Moreton Basin have shown that a revision of nomenclature is required for units in the Late Triassic to Early... -
Interactions between saline redbed groundwaters and peritidal carbonates,...
A commonly cited model for the genesis of stratiform Cu deposits that lack either igneous or hydrothermal associations has been tested in modern environments, on the... -
