漳州复式岩体岩石谱系单位划分及成因分析

THE ROCK PTDIGRCE UNIT DIVISION AND PETROGENESIS ANALYSIS OF ZHANGZHOU GRANITE BATHOLITH,FUJIAN PROVINCE

漳州复式岩体按成分和结构的演化特点，可划分为７个单元，并归并为漳州序列和新村序列；按其岩石学、岩石化学和地球化学特点，漳州序列为Ｉ型花岗岩，形成于早白垩世压性构造环境，而新村序列为Ａ型花岗岩，形成于晚白垩世张性构造环境。

From the viewpoint of comagmatic evolution and using the mothod of rock pedigreeunit division,Zhangzhou grailite batholith in southeastern China are devided into seven units andincoporated into zhangzhou sequence and xincun sequence , Zhangzhou sequence has the character-istics of I type granite , but Xincun sequence is considered to be A type granite because of itsAnorogenic and subalkalline characteristics. Zhangzhou sequence is formed in active continentalmargin and compressive tectonic envionment from preplate collision to post- plate collision uplift e- poch. Xincun sequence is dominantly formed in a special rift-like , extensional envionment in post-orogenic or anorogenic epoch.
