| 摘 要： | 兰田埠岩体是一个具有两次岩浆活动的复式岩株，岩体侵入寒武系、震旦系，使围岩发生了热变质作用，同位素年龄值Ｕ─Ｐｂ法３６７Ｍａ（宜昌所，１９９０），属加里东晚期岩体。根据与侵入体协调一致的围岩构造、岩体内部构造，兰田埠岩体是一个典型的斜向底辟侵入，类热气球膨胀模式的岩体。

| Abstract: | Nantianpu rock mass is a complex stock which took place two mag-matisms. The body intruded into the Cambrian system and Sinian system,thus the country rock underwent the thermal metamorphism. The U-Pd me-thod 367Ma of isotopic age value(Yichang Institute,1990)belongs to thelate Caledonian rock mass. Based on the structure of wall rock and thestructure inside the body coincided with intrusive,Nantianpu rock mass isa typical body with oblique diapir intrusion and class hydrogen ballon ex-pansion model. |
