新疆福海县蒙库地区早二叠世侵入岩成因与成岩方式探讨

An Approach to the Genesis and Petrogenetic Style for the Early Permian Intrusions in Mengku,Fuhai,Xinjiang

新疆福海县蒙库地区早二叠世侵入岩序列主要侵位于中元古界苏普特岩群、震旦系富蕴群与上石炭统喀喇额尔齐斯组地层中,延伸不连续,呈单个岩体出露,出露面积均较小,总体上呈北西-南东向、条带状分布,与区域构造线方向一致,反映了区域构造对侵入体的的控制作用。岩体平面上呈平行舌状,岩体与围岩发生较强的交代作用,其边缘附近发育大量大小不一的围岩捕虏体,并见岩枝贯入围岩。文章就蒙库地区早二叠世侵入岩成因与成岩方式进行了探讨。

Early Permian intrusions in Mengku, Fuhai, Xinjiang were mainly emplaced in the Middle Proterozoic Supute Group, Sinian Fuyun Group and Upper Carboniferous Kalaeerqisi Formation. They occur as stock in N-S trending belts parallel to regional lineament, showing structural control. This paper makes an approach to genesis and petrogenetic style for these intrusions.
