摘    要:本区的成矿断裂是发育在太古代太华群中韧性剪切带之上的一系列脆-韧性、脆性剪滑断裂。在成矿过程中,不同类型断裂、不同类型构造岩带显示出不同的断裂动力蚀变特征和成矿元素组合。活化的金等元素在构造应力驱动下,于不同构造部位以不同形式沉淀并富集成矿,从而形成了蚀变岩型和石英脉型金矿体。

关 键 词:成矿断裂,韧性剪切带,脆-韧性剪滑断裂,葫芦沟金矿床,陕西

TECTONIC GEOCHEMICAL FEATURES OF THE HULUGOU GOLD METALLOGENIC FAULT OF SHAANXI
Abstract:The metallogenic fault system of the Hulugou gold deposit is composed of a senries of brittle-ductile or brittle shear-slide faults in the ductile shear zones of the Taihua gtoup(Ar). Analysis of its geochemistry shows that fault and fault-rock zones have differences in their metasomatic features and combinations of metallogenetic elements. Remobilized gold and other elements were forced by compressive stress to migrate to structural zones of accumulation.These regions conltain both metasomatic and quartz vein type gold ore bodies.
Keywords:metallogenic fault  ductile shear zone  brittle shear fault  hulugou gold deposit  shaanxi
