The Upper Devonian to Lower Carboniferous Drummond Basin sequence crops out over an area of approximately 25 000 km2 , mainly west but also east of the Anakie Inlier in east-central Queensland. The Drummond Basin is a structural remnant of a large intermontane depositional basin that developed in the Tasman Geosynclinal zone after the Tabberabberan Orogeny. It received up to 12 000 m of predominantly fluviatile sediments which were transported into the basin by a northerly flowing river system. There may have been some marine incursions. Basement to the basin consists of early Palaeozoic slightly metamorphosed sediments and granite. Sedimentation in the Drummond Basin ceased at the onset of the Kanimblan orogenic event, during which the sequence was folded and uplifted to form a structural high shedding detrital material into the Bowen and Galilee Basins.
