| 摘 要： | 马泉金矿床四号矿带位于秦蛉造山带西秦岭中部花岗岩带，属于北中秦岭陆表海盆中段，赋存于高桥一洮坪大断裂西段。经矿床特征分析认为，成矿物质主要来源于地层，成矿溶液主要来源于大气降水，有少量变质水加入。文章总结了矿床控矿因素、围岩蚀变及找矿标志，探讨了矿床成因，认为属中低温热液型金矿床。

| Abstract: | No. 4 ore zone of Maquan gold deposit exists within the granite zone in the middle part of west Qinling of Qinling orogenic belt, belong to the west section of Gaoqiao-Taoping Faults. Analysis of deposit characteristics show that metallogenetic material came from the strata, most the source metallogenetic solution was of wall rock, criteria for prospecting, and support that the deposit is middle-low hydro-thermal type gold deposit. |
