THE COOPER'S CREEK BASIN

Abstract

Results of past surface and subsurface geological and geophysical surveys indicate that the Cooper's Creek area has been a sedimentary basin from Lower Palaeozoic time to at least the beginning of Cretaceous time.

The Cooper's Creek Basin is bounded to the east by the Canaway Ridge, to the south by a basement ridge that runs from Naryilco to Kopperamanna, to the north by a folded trend that runs from Warbreccan to Kopperamanna.

Sediments from Cambrian to Recent age have been encountered in wells drilled by Delhi-Santos. It is postulated that the present basin originated in post-Siluro-Devonian time after the Bowning orogeny.

Physiographically the axis of the basin is reflected by the Cooper's Creek.
