Excavations near Balickera, New South Wales displayed a perfectly exposed, thick sequence from which is described rock units and type sections of Carboniferous sediments and volcanic rocks that were formerly assigned to the " Basal ", " Volcanic " and " Glacial Stages " of the " Kuttung Series ". The stratigraphic section includes zeolite facies sediments and volcanic rocks, carbonaceous strata that give the earliest evidence of coal forming conditions in the Hunter Valley, well defined floral zones, and a perfectly exposed succession of volcanic and pyroclastic rocks of a basalt andesite rhyolite association. The section is a critical base for special studies relating to a period when world climate was changing and polar wandering or drift was possibly in progress.
