摘要
白干湖金矿床是近年来西安工程学院发现的重要金矿床之一 .该矿床属与浅成斑岩有关的石英脉型金矿床 .含金石英脉体产出于石英斑岩与灰岩的接触带 ,成矿物质主要来自石英斑岩围岩 ;流体萃取周围介质中的成矿元素 ,集中于接触带中 ,金富集沉淀成矿 .矿床形成分热液成矿期和表生氧化期 ,其中热液成矿期又分黄铁矿 -毒砂 -石英阶段、金 -黝铜矿 -方铅矿 -闪锌矿 -石英阶段、石英 -碳酸盐阶段 .
The Baiganhu gold deposit is one of the most important deposits discovered by Xi'an Engineering University recently. The deposit is a quartz vein type gold deposit concerned with hypabyssal porphyry. The mineralization materials of this type of gold deposit are chiefly from the hosting quartz porphyry. The mineral vein occurs in the contact strip of the quartz porphyry and the limestone. The fluid extract the metallogenic element of the surrounding medium concentrates in the contact strip and gold concentrates and precipitates. The deposit underground thermal ore forming phase and surface oxidation phase. The thermal ore forming phase consists of a pyrite arsenopyrite quartz stage, a gold tetrahedrite galena sphalerite quartz stage and a quartz carbonate stage.
