| 摘 要： | 湖南南部燕山早期香花岭岩体主要由铁锂云母二长花岗岩组成。岩石SiO：和K2O平均含量分别为73．72％和4．78％，Na2O＋KO平均8．47％，K2O／Na2O比值平均为1．40，A1：03平均为13．81％。总体属强过饱和铝质钙碱性一碱性花岗岩类。氧化物构造环境判别图解及区域构造演化背景反映香花岭岩体形成于后造山构造环境。

| Abstract: | The Early Yanshanian Xianghualing granites in southern Hunan consist dominantly of ironlithium mica monzonitic granites. Their mean content of SiO2 is 73.72%, K20 4.78%, Na20 ＋ K20 8.47% with mean K2O/Na2O ratio 1.40 and A1203 13.81%. Thus, the rocks belong to strong peraluminous calc - alkaline to alkaline series. Multiple oxide - diagrams for discrimination of structural environment and regional tectonic evolution background indicate that the rocks were formed in a post - orogenic extension environment. |
