摘要:
早子沟金矿床位于西秦岭造山带的夏河—合作地区，是夏河—合作地区乃至西秦岭造山带经济价值最高的金矿床之一。基于早子沟金矿床找矿勘探新近发现的地质现象，对早子沟金矿床地质和金矿化特征进行了系统总结，结合前人年代学数据,对微细浸染型/细脉状毒砂-黄铁矿型和脉状石英-辉锑矿-自然金型2类金矿化的成矿时代和矿床成因进行探讨，认为二者成矿时代相差较大，可能存在不同的源区。早子沟金矿床2类金矿化分别在浅部岩体周围断裂发育部位和深部低角度断裂发育部位显示出了较好的成矿潜力，应作为下一步找矿勘探的重点。

Abstract:
Zaozigou Gold Deposit is located in the Xiahe-Hezuo area of the West Qinling orogenic belt,and is one of the most economically valuable gold deposits in this area and even the entire West Qinling orogenic belt.Based on recent geological discoveries in the exploration of Zaozigou Gold Deposit,the geological and mineralization characteristics of the deposit were systematically summarized.Combining previous geochronological data,2 types of gold mine-ralization,namely the micro-fine dissemination narrow-vein arsenopyrite-pyrite type and the vein quartz-stibnite type,were discussed in terms of their metallogenic ages and deposit genesis,indicating a significant difference in their metallogenic ages,suggesting the possible existence of different source areas.The 2 types of gold mineralization at Zaozigou Gold Deposit show good prospecting potential in the areas with developed fractures around shallow rock bodies and on areas with low-angle fractures at depth,highlighting the importance of focusing on these areas for future prospecting exploration.
