摘要： 四川盆地普光大气田发现后,许多学者对其所在的沉积-构造位置有不同的称谓。从板块构造学和峨眉地裂运动的观点,建议统一称其为拗拉槽。在此认识的基础上,预测川西存在绵竹—中江拗拉槽,近期在川中发现的“蓬溪—武胜台凹”得到证实。扬子板块西北缘发育的鄂西、广旺—开江—梁平拗拉槽和绵竹—蓬溪—武胜拗拉槽群,系3 种地质构造因素综合作用的结果,但主控因素是峨眉地幔柱产生的地球动力学作用,在这些地区有优越的天然气勘探远景。

Abstract: The tectonic-sedimentary setting of Puguang gas field in Sichuan basin was differently named by researchers when it was discovered. This paper suggests a terminology of aulacogen for the setting from point of view of plate tectonics and Emei taphrogeny, by which existence of Mianzhu-Zhongjiang aulacogen in western Sichuan basin is predicted and confirmed with the discovery of Pengxi-Wusheng concave platform in central Sichuan. It is concluded that the west Hubei, Guangwang-Kaijiang-Liangping and Mianzhu-Pengxi-Wusheng aulacogen groups developed in the western margin of Yangtze platform are resulted from the integrated process of three geological tectonic elements, and the dominant contributor is the dynamics of Emei mantle plume. These aulacogen groups possess potentials of natural gas prospecting.

Key words: Emei mantle plume, Emei taphrogeny, basalt, Aulacogen, natural gas, exploration potential
