| 摘 要： | 鄂西香溪地区中二叠统发育良好。重新观察发现 :新滩剖面的马鞍段并不缺失 ;茅口组与吴家坪组之间的粘土岩应归属于吴家坪组 ;隐石燕 (Cryptospirifer)是与瘤状构造同源的再沉积埋葬。同时探讨了香溪及邻区中二叠世构造古地理演化轮廓及沉积格局 ,研究区栖霞期和茅口期的沉积相“大同小异”。

| Abstract: | The Middle Permian strata is well-developed in the Xiangxi area, Western Hubei. The existence of the Ma'an Member in Xintan Section and the position of the Clay Member between the Maokou and the Wujiaping Formations was disputed in early researches. According to our recent observation, the Ma'an Member exists in the Xintan Section, and the Clay Member should be incorporated in to the latter. In addition, Cryptospirifer is the reworked fossils cognate with nodular structure. The Middle Permian palaeogeographic, developing outline and framework of the Xiangxi area and its neighbourhood are discussed also. |
