The Georgina Basin is a Neoproterozoic to Lower Devonian sedimentary basin covering 325 000 km2 of western Queensland and the Northern Territory. It is a northwest-southeast-trending extensional basin, with conventional and unconventional hydrocarbon exploration targets in the southern depocentres within the middle Cambrian Arthur Creek Formation (AC Fm). Recent biostratigraphic work using agnostid trilobites [1] has determined that the prospective hot shale (so called due to high gamma-ray log values) at the base of the AC Fm in the Dulcie Syncline is older (Templetonian) than thehot shale in the Toko Syncline, which is of Floran age. To complicate the stratigraphy further, the Thorntonia Limestone (Th Lst) in the Undilla Sub-basin is also Templetonian in age, the same age as the AC Fm in the Dulcie Syncline and younger than the Th Lst in the Dulcie Syncline (Ordian). In this study molecular analyses of the AC Fm and the Th Lst from the CKAD0001 well were undertaken in order to distinguish between the two formations and assist with future correlations.
