| 中文摘要: |
| 小柳沟钨矿床石英脉中Cu,Mo关系密切,相伴而生,对围岩选择性较小,而W则对围岩选择性大,主要集中富集于夕卡岩及角闪云母片岩中。走向NE向、NW向和近EW向的石英脉在矿区发育,在夕卡岩及角闪云母片岩中可富集成矿,而在其他岩性围岩中形不成具有工业意义的白钨矿体。今后评价重点应为走向近EW向、倾向S的石英脉,该组石英脉最为发育,在矿区深部石英网脉中可富集成矿,品位0.480%~0.682%;其他组别石英脉在矿区分布零乱,仅在局部地段密集成带,其评价意义不大。 |
| 英文摘要: |
| This article makes a detail describption on characteristics in quartz veins of Xiaoliugou wolfram deposit. After discussing the relationship between quartz veins and wolfram(molybdenum, copper), the author points out that there is a close relationship between molybdenum and copper in quartz veins, and they usually occur together, and their mineralization hardly depend on wall rocks. However, wolfram mineralization in quartz veins mainly depend on wall rocks, and wolfram usually enriches in skarn and hornblende-mica schist. There are lots of NE, NW and EW quartz veins, especially EW quartz veins. And N usually enrichs to ore bodies in skarn and hornblende-mica schist, but hardly enrichs to ore bodies in other wall rocks. So in the future, working on quartz veins should aim at the EW groups, and the other groups is worthless. Because EW quartz veins ore concentrated to three zones, and the other quartz veins distributed dispersedly. |
