| 1 | Mesozoic lithofacies palaeogeography and petroleum prospectivity in North Carnarvon Basin,Australia显示文摘The North Carnarvon Basin, which lies in the North West Shelf of Australia, is highly rich in gas resources. As a typical passive marginal basin, it experienced the pre-rifting, early rifting, main rifting, late rifting, post-rifting sagging and passive margin stages. The basin was mainly filled with thick Mesozoic-Cenozoic sediments, of which the Mesozoic hosts the principal source, reservoir and seal intervals. Mesozoic palaeogeography has an important control on the oil and gas distribution. Triassic gas-prone source rocks of deltaic origin deter-mine the high endowment of natural gases in the North Carnarvon Basin. The more restricted distribution of oil accumulations is controlled by oil source rocks in the Upper Jurassic Dingo Claystone. The Muderong Shale deposited in the Early Cretaceous marine transgression provides the effective regional seal for the underlying oil and gas reservoirs. | Tao Chongzhi Bai Guoping Liu Junlan Deng Chao Lu Xiaoxin Liu Houwu Wang Dapeng | 2013 | Journal of Palaeogeography2013，2，1： | 7 |
