| 摘 要： | 本文应用同位素地质方法研究322矿田内花岗岩的年龄和成因、成矿热液和成矿物质来源等问题。研究表明,矿田内的成矿母岩为改造型花岗岩,其Rb-Sr同位素年龄为198.8Ma,成矿热液来自花岗岩结晶矿物颗粒间和裂隙中的溶液以及大气降水。成矿物质主要来自花岗岩,部分也来自岩体周围的寒武系地层。

| Abstract: | In this paper the method of isotope geology is applied to study theage and origin of granite, sources of hydrothermal solution and orematerials in ore field No. 322. The study indicates that the host rock inthe ore fiel is the transformation type granite, its isotopic age of Rb-Srbeing 198.8 ma. The hydrothermal solution of mineralization comes fromthe solution which lies between the crystalline mineral grains and thecrack of granite, and meteoric water. The ore materials mainly come fromthe granite and partly from the Cambrian strata around the rock body. |
