Organic petrography and origin of condor coals from Hillsborough Basin, Queensland

The aims of this study are to determine the characteristics of the Condor coals and use these data to provide a better understanding of the depositional environments of the coals. Seventytwo samples from three drill holes that intersected the Lilypool subunit of the Lethebrook unit were examined. The Lilypool subunit is part of the Tertiary Hillsborough Basin sequence that comprises mostly oil shale with coal, shaly coal and fine-grained clastic sediments.
