| 摘 要： | 西秦岭地区，构造、岩浆活动发育，成矿地质条件优越，是我国微细浸染型金成矿集中区，具有较好的找矿前景。格尔托金矿属微细浸染型金矿床，宏观上受三叠系地层控制，矿体就位于断层带内部或与闪长岩脉相伴。围岩蚀变为硅化（似碧玉岩化）、绢云母化、碳酸盐化和绿泥石化。主要矿化为褐铁矿化、赤铁矿化和黄铁矿化。金的成矿与硅化、赤铁矿化关系密切，是强烈的矿化地段和金矿体富集部位，也是重要的找矿标志。

| Abstract: | In Western Qinling Mountain area,tectonic-magmatie activity development,the metallogenic geological conditions are predominant,where is micro-disseminated gold deposit concentration area in China and has a good prospecting.Geertuo gold mine is a micro-disseminated gold deposits which controled by Triassic strata macroscopically,ore body is located within the fault zone or accompanied by diorite dykes.The wall rock alterations are silieification,sericitzation(jasperoidization),carbonation and chloritization.... |
