括苍山地区燕山晚期花岗岩岩石谱系单位的建立

运用花岗岩岩石谱系单位的新理论、新方法 ,将括苍山地区在燕山晚期形成的花岗岩 ,按岩石谱系单位的建立原则 ,共建立了15个单元。在此基础上进一步把空间上紧密伴生、时间上比较接近、成因上有一定联系、成份和结构上具亲缘关系的十四个花岗岩单元 ,归并成三个超单元 ,其余一个单元为独立单元。系统地研究了各单元的地质特征、岩石学、岩石地球化学特征 ,确定了各超单元的含意 ,再依据超单元组合的归并原则 ,将三个超单元归并为括苍山超单元组合。为浙东南区花岗质岩类的深入研究提供了基础性资料。

Establishment of the Rock Lineage Unit for LateYanshanian Granite in Kuocangshan Area

By applying new theories and new methods on the rock lineage unit of granite,15 rock lineage units are established for the granite formed during late Yanshanian Period in Kuocangshan.On this basis,3 super_units are merged from 14 granite units which are associated in space,close in time,related in genesis,and affiliated in composition and texture.The left one is a independent unit.The authors systematically studied the geological features,petrology and lithogeochemical characteristics of every unit,defined the meanings of the super_units,and furthermore,combined the 3 super_units as Kuocangshan super_unit pattern.It provides basic data for further research on the granitic rocks in southeastern Zhejiang.
