| 摘 要： | 南秦岭南部构造带具备较好的金矿成矿条件与成矿背景，是该区域规模较大金矿带.金沟矿段是黄龙金矿床最主要的组成部分，该矿段矿石中磁黄铁矿和黄铁矿发育，其中磁黄铁矿矿石是矿床中含量最高的硫化物矿石.磁黄铁矿存在两种产出状态，分别为早期形成的呈浸染状、团块状分布的磁黄铁矿与晚期形成的脉状磁黄铁矿.成分分析结果表明以单斜磁黄铁矿为主.该矿床属中-低温矿床.微量元素结果显示富Co贫Ni，与金矿化关系密切.在含金性方面，脉状产出的磁黄铁矿优于团块状分布的磁黄铁矿，且脉体越细含金性越好，因此细脉状磁黄铁矿可作为该区重要的找矿标志.

| Abstract: | The tectonic belt in the south of Southern Qinling Mountains is a large-scale gold ore belt with good metallogenic conditions. The Huanglong gold deposit mainly consists of Jingou ore block, in which pyrrhotite and pyrite are developed. The pyrrhotite ores contain the highest sulfide in the deposit. The pyrrhotite minerals, majorly monoclinic pyrrhotite by component analysis, occur in two statuses, i.e. early-formed disseminated and lumpy type and later vein-type. The deposit belongs to epi-mesothermal type. The trace element analysis results show the pyrrhotite is characterized by rich Co and poor Ni, closely related to gold mineralization. In terms of gold-bearing property, the vein-type pyrrhotite is superior to lumpy type. The finer the vein is, the higher the gold content is. Therefore, veinlet pyrrhotite can serve as an important prospecting indicator in the area. |
