| 摘 要： | 本文以同源岩浆演化理论为指导思想，对组成商城岩体的楼坊湾、石鼓洼、肆顾墩三个单元，从其地质特征、岩石结构、构造、矿物成分及岩石地球化学特征等方面的演化规律，进行了较为详细的研究。认为其是由同一构造－热事件所产生的同源岩浆，经过三次涌动上侵所形成的复杂深成岩体。并且在岩石成因类型上为具有Ｉ型花岗岩地球化学特征的Ｓ型花岗岩。

| Abstract: | The theory of comagmatic evolution is guiding ideology in the paper,the evolutionarylaw of rock structure,structure,mineral composition,the characteristic of lithogeochemistryof Loufangwan,Shiguwa,Sigudun units,which consist of Shangcheng rock body have beenstudied in detail.These units are thought comagma produced by syntectonic-heat event,andhave inrushed three times then formed complex pluton. It is S-type granite which havinggeochemitry characteristics of I-type granite in genetic type. |
