L077 Flinders River seismic survey, QLD, 1966

In the severi months from the beginning of May to the end of November 1966, the Bureau of Mineral Resources carried out a seismic survey on the Flinders Regional Gravity Low in north-central Queensland. The first six months of the survey were spent in investigating the sedimentary section between Richmond and Julia Creek, particularly to determine whether there was any appreciable thickness of Palaeozoic sediments. The seismic results proved that basement was reasonably shallow and that no appreciable thickness or Palaeozoic sediments can be expected in the area. One month of the survey was then devoted to seismic work near Bowen Downs Homestead, north of Aramac, in an effort to determine the location of the western margin of the Drummond Basin. This work demonstrated that sediments of the Drummond Basin increase in thickness rapidly to the east in the area surveyed.
