摘要
通过构造解析证实,山西中条山北峪花岗岩体内各类定向构造分别为岩浆流动构造、边缘片理带和韧性剪切带。对各类捕虏体尤其是新发现的相当于中条群余元下组透闪石大理岩捕虏体和岩浆侵位机制的研究推断,北峪花岗岩体为中条晚期底劈侵位(伴有顶蚀作用、气球式膨胀作用)的岩浆岩体。
Based on the detailed structural mapping anc1 analysis, three types oforiented structures within Beiyu granite body are recognized as follows:flow structures, marginal schistosity zone and ductile shearing zones.Combining with the study of xenoliths, especially the newly discoveredxenoliths of tremolite marble belonging to Yuyuanxia Formation of ZhongtiaoGroup and the study of emplacement mechanism of magma, the authorconcludes that the granite is magmatic and emplaced briefly by diapirism(accompanied by stopping and partial ballooning ) in the late stage ofZhongtiao movement.
