| 中文摘要: |
| 小柳沟铜钨矿赋存于长城系朱龙关群中,其中以赋存于云母角闪片岩、夕卡岩夕卡岩化灰岩中的似层状矿化为主,矿体规模大,品位高,矿物成分复杂,围岩蚀变发育。其次为赋存于岩体接触带的夕卡岩型似层状、透镜状矿体,矿体规模较大,但品位低,矿石成分简单,围岩蚀变较发育。另外还有赋存于石英网脉带中的脉状矿体,矿体规模小,品位较低,矿石成分简单,围岩蚀变较发育。根据对矿区控矿条件及矿化富集规律的研究,今后该矿区找矿靶区为:小柳沟铜钨矿区西矿段西部及北部、北矿段及东矿段中的云母角闪片岩、灰岩及, 级重砂异常分布区,隐伏花岗岩体及地表花岗岩枝与围岩的接触带,石英网脉带脉。 |
| 英文摘要: |
| There are four tungsten deposits discovered in Xiaoliugou mining district. Mineralization of Xiaolingou Cu-W deposit occurs as layered form in mica-amphibole schist, skarn and skarnized Limestone. The deposit is characterized by large size, high grade, complex mineralogy of ore bodies and strong wall rock alteration. Shiji Cu-W deposit is characterized by layered mineralization only in mica-amphibole schist, larger size, high grade and complex mineralogy of ore bodies and strong wall rock alteration; Guishan Cu-W deposit by the dominant layered mineralization in mica-amphibole schist, small size, low grade and simple mineralogy of ore bodies and strong alteration. The west part of Xiaoliugou deposit, the west and north parts of Shiji deposti and mica-amphibole schist in east part of Guishan deposit are the potential targets for future exploration. |
