Carnarvon Basin

The Carnarvon Basin is a geological basin located in the north west of Western Australia which extends from the Dampier Archipelago to the Murchison bioregion,[1][2] and is the main geological feature that makes up the North West Shelf.

[3] The main sub-basins for petroleum exploration in the basin have been Dampier, Exmouth and Barrow.

[4] The Southern basin consists of the Gascoyne, Merlinleigh, Bidgemia and Byro Sub-basins and Bernier Platform and is flanked to the east by the Archaean Pilbara Block.

[3] The Gnargoo structure, which has remarkable similarities to Woodleigh crater, is a proposed 75 km impact crater on the Gascoyne Platform, Southern Carnarvon Basin with an estimated age of 100-300 Ma.
