Blair Athol (BAC) is located within the Blair Athol Basin, an isolated Permian aged geological basin near the western edge of the northern Bowen Basin. The site geology is comprised of five main lithological units, listed below from youngest to oldest:
? Tertiary and Quaternary alluvial deposits (TQa and Qa) developed within the ephemeral streams that drain the site, including Bath Creek and Washpool Creek.

? Tertiary basalt (Tb) in the north and east of the ML, with an average thickness of 18 to 22 m within the lease.

? Permian Blair Athol Coal Measures (Pa) which comprise:
- the upper coal measures, which include sandstone, siltstone, mudstone, conglomerate, as well as the four main coal seams of the basin (referred to as Seams 1, 2, 3 and 4); and
- the lower coal measures, which include basal conglomerate, sandstone, siltstone, and mudstone with an estimated maximum thickness of 130 to 150 m.

? Early to middle Devonian arenites, present as a small basement trough in the southern part of the basin.

? Proterozoic/Cambrian Anakie Metamorphic Group, comprising schist, phyllite and metabasalt.

As noted by JBT (2012), the basement metamorphics, Blair Athol Coal Measures, Tertiary basalts and Quaternary alluvium all occur at surface in different areas of the BAC ML.
