The onshore part of the Carnarvon Basin covers about 115,000 km² and the offshore part covers approximately 535,000 km² with water depths up to 3,500 metres. It is separated into two major areas - the Northern Carnarvon Basin, and the Southern Carnarvon Basin. ==Northern Carnarvon Basin== The Northern Carnarvon Basin includes the Exmouth Plateau, Wombat Plateau (on the northern part of the Exmouth Plateau), Investigator Sub-basin, Rankin Platform, Exmouth Sub-basin, Barrow Sub-basin, Dampier Sub-basin, Beagle Sub-basin, Enderby Terrace, Peedamullah Shelf and the Lambert Shelf.〔(Geoscience Australia - Northern Carnarvon Basin (NCB) )〕 The main sub-basins for petroleum exploration in the basin have been Dampier, Exmouth and Barrow.〔(Geoscience Australia - Petroleum exploration (NCB) )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Carnarvon Basin」の詳細全文を読む スポンサード リンク
