Deposition, in the Late Devonian to Early Carboniferous, of approximately 12,000 metres of almost entirely fluvial sediments, occurred in the extensional, foreland environment of an adjacent, easterly migrating magmatic arc. There was some volcanic input from this arc and minor marine deposition occurred early in the basin's history.

The northern Drummond Basin appears to have undergone three separate, major tectonic events; extension in the Late Devonian to Early Carboniferous, uplift in the Mid to Later Carboniferous, which produced a low angle unconformity between the Drummond and the overlying Galilee Basin, and Mid to Late Triassic compression.

Interpretation of the seismic lines recognised the structural style of the northern Drummond Basin to be essentially compressive. Analysis of faults, both along the lines and by projection of them onto a subsurface horizon, has shown the basin to have undergone structural inversion.

Recent theories on the Late Palaeozoic evolution of eastern Australia, outlined several structural models which place the evolution of the Drummond Basin in a regional context.

Maturation and source/reservoir studies have shown the northern Drummond Basin, in the study area, to be unprospective for hydrocarbons.
