| 中文摘要: |
| 梅子沟金矿区位于华北古板块与扬子板块的接合部位——秦岭多金属成矿带东段朱夏断裂带中部,两侧被深大断裂所夹持,构造、岩浆活动分为多期,且频繁叠加。研究区赋矿岩石主要为碳硅质板岩,最主要的控矿、导矿及容矿断裂为纵贯本区的红石崖—水洞岭韧性剪切带,该区圈定的15个金矿体,都产在韧性剪切带中。研究分析了梅子沟金矿床特征、找矿标志,总结了矿床成因,认为矿床类型为变质—热液型矿床。 |
| 英文摘要: |
| The Mei Zigou gold mine is located in the middle part of the Zhuxia fault zone in the eastern part of Qinling polymetallic ore belt,which is located in the junction of the northern part of the North China ancient plate and the long-term active belt of Yangzi plate. Two sides of the mine area are held by deep and large faults, and in where the tectonic and magmatic activity are divided into many stage and frequently superposed. In the study area,the ore-bearing rocks in the Meizigou gold mine are mainly carbon-silicon slate,the most important ore-controlling and ore-leading fault is the Hong Shiya-Shui dongling doctile shear zone,which runs through this area. The 15 gold ore bodies delineated in this area,they are all existing in the ductile shear zone. This study analyzed the characteristics and the prospecting signs of the Meizigou gold deposit,summarized the genesis of the deposits.It is considered that the type of the deposits is metamorphic-hydrothermal deposit. |
