摘要
按照构造-岩性法填图方法和“灰色片麻岩”概念论述了冀东青龙三家地区金矿床的成矿地质背景及矿床地质特征,指出燕山期重熔花岗岩类、太古界变质岩系、韧性剪切带和脆性断裂是控制本区金矿床形成的重要因素。
According to the structure-rock mapping method and the 'grey gneiss'concept, the metallogenic geological background and ore deposit geologicalfeatures of the Sanjia gold deposit are expounded. It is indicatcd that theYanshanian granitoid magmation, Archean metamorphic rock series, ductileshear zone and crisp fractures are three major important factors controllingthe formation of the Sanjia gold deposit.
