摘要
本文从地质特征、退化变质作用、构造地球化学以及成矿机理等方面探讨了研究区金矿的韧性剪切带成因.韧性剪切带是一个地球化学活动带,具有金及有关元素迁移、聚集和成矿的有利条件.乌兰布浪沟金矿是一个典型的韧性剪切带型金矿.
On the grounds of geological features, regressive metamorphism, tectono-geochemistry and metallogenetic mechanism, the origion of the ductile shear belt in the investigation area is discussed. The belt is a geochemically active zone and is favourable for the migration, concentration and oreforming for gold and related elements. The Ulan Bulanggou gold deposit belongs to the typtical ductile shear belt type
