| 摘 要： | 本文对海南二甲和不磨金矿区的围岩和矿石进行了年代学研究。结果：二甲和不磨金矿区的围岩和矿石的年龄主要在２２０～３９０Ｍａ之间，表明主要的混合岩化，糜棱岩化作用和金矿化作用发生在海西—印支期，以印支期为主，燕山期构造运动和矿化作用的迭加改造对金矿的富集有一定影响。

| Abstract: | Results of chronalogical study of Erjia Au mine area and Bumo mine area are presented in this paper. Age values of wall rock and ore of An deposits in the two areas are in the range of 220-390Ma. Migmatization, myllonitization and An ore forming took place in Hercynian and Indo-China Periods and Indo-China Period is the main An ore-forming epoch. Yanshanian tectonic magmatism could modify and enrich the protore of Hercynian, Indo-China periods. |
