| 中文摘要: |
| 西秦岭地区金矿床是中国重要金矿资源基地之一，李坝和金山金矿床是中川地区大型金矿床。本文在收集整理并分析以往资料基础上，对甘肃李坝—金山矿集区进行了野外实地调查研究，并对该地区的成矿规律进行了总结。认为该地区的控矿构造主要因素是中川杂岩体侵入构造作用叠加了区域褶皱+断裂复合构造系统，并从力学角度对中川杂岩体的侵位给 2个矿区施加的应力进行分析，结合区域物化探信息构建了李坝—金山矿集区金矿床综合信息找矿预测地质模型，最后在李坝矿区圈定了 3处找矿预测潜力区，在金山矿区圈定了 2处找矿预测潜力区，以期供矿山企业深边部找矿预测提供参考。 |
| 英文摘要: |
| The gold deposit in the Western Qinling area are one of the important gold resource bases in China.Based on the collection, collation and analysis of previous data, this paper conducted field investigation and re.search on the Liba -Jinshan mineral concentration area in Gansu Province, and summarized the mineralizationregularity of this area. It is believed that the main controlling factors of ore deposits in this area are the intrusivestructures of the Zhongchuan complex rocks superimposed on the regional fold + fault composite tectonic system.The stress exerted by the intrusion of the Zhongchuan complex rocks on the two mining areas was analyzed from amechanical perspective. Combined with regional geochemical and geophysical exploration, a comprehensiveinformation-based geological model for gold deposit explortaion prediction in the Liba -Jinshan mineralized cluster was constructed. Finally, three potential exploration areas were delineated in the Liba mining area and two in theJinshan gold mining area, providing references for deep and peripheral exploration prediction for mining enterprises. |
