The succession in three districts is described and correlated. Glacial deposits at the base of sections are followed by a variety of marine and lacustrine or estuarine sediments. Correlations are made with Russia, India, and Timor. The Permian glaciation of Australia was a single major event, severest during the Sakmarian, and a major interglacial period succeeded by less severe conditions during the Artinskian. The upper Paleozoic strata of Western Australia were deposited in a geosynclinal trough marginal to the pre-Cambrian shield. The relative geographical position of Australia and the East Indies in late Paleozoic time must have been very much the same as at present. An extensive bibliography is added.
