甘肃省天水市望天沟金矿地质特征及成因分析

摘要

Based on the analysis of the ore body features ,mineralization and gold bearing in rocks ,it is believed that Wang-tiangou gold mine is controlled by NE fractures .The industrial type of Wangtiangou gold deposit is composed of quartz vein type and altered rock type , and it belongs to meso-hydrothermal fluid-filled gold mine .%本文通过对望天沟金矿矿体特征、赋存规律及矿化特征分析认为，望天沟金矿成矿受与北东向断裂构造的形成及发展相关，工业类型为构造蚀变岩型和石英脉型金矿的混合类型，成因上属于热液充填交代矿床。
