摘要: 鄂西地区在中晚二叠世,随着古特提斯洋的打开 ,在区域性拉伸构造背景控制下,由海湾向海槽转化,并发展成中上扬子碳酸盐台地东北边缘上的一个台间裂陷(槽),它受控于建始-郁山-彭水断裂。该台间裂陷(槽)对川东-鄂西地区晚二叠世-早三叠世台地沉积相和生物礁分布具有重要的控制作用。

Abstract: In the Middle-I ate Permian, with the open of paleo-tethys, on the regional tension background, the westerm Hubei provinct(Exi area) was transformed from the gulf into the trough, and developed into an inter-platform rift (trough) in the northesterm margin of carbonate platform in the Middle -Upper Yangtze block, which was controlled by Jianshi-Y ushan-Pengshui fault. This inter-platform rift (trough) plays an important role in the control of sedimentary facies and distribution of the organic reefs of Late Permian- -Early Triassic in eastem Sichuan and Exi area.

Key words: Exi rift trough, Late Permian, silieous rock, Jianshi-Yushan-Pengshui fault, platform-edge reef bank, marine oil-gas geology
