| 中文摘要: |
| 内蒙古关东沟铜多金属矿位于撰山子—各力各金成矿带内,为该带内新发现的中低温岩浆热液型铜多金属矿床。通过地、物、化及地表工程揭露等多种工作手段,在矿区两条蚀变带中共圈定出2条铜多金属矿体,长50~120 m,厚4.1~12.5 m,Cu品位0.30%~2.94%,Ag品位34×10-6~94×10-6。本文在总结关东沟铜多金属矿床地质特征及成因模式的基础上,通过与区域典型矿床特征进行对比,总结了矿床找矿标志,为赤峰地区铜多金属矿提供找矿方向。 |
| 英文摘要: |
| The Guandonggou copper polymetallic deposit is located in the Zhuanshanzi-Gelige gold metallogenic belt, Inner Mongolia. It is a newly discovered medium-low temperature magmatic hydrothermal copper polymetallic deposit in periphery of the Zhuanshanzi gold deposit. Based on geological, physical, chemical, remote work and surface engineering exposure, two alteration zones were identified in the Guandonggou copper polymetallic deposit. Two copper polymetallic ore bodies were delineated, which are 50~120 m in length and 4.1~12.5 m in thickness, with Cu grade of 0.3%~2.94% and Ag grade of 34.1×10-6~94.3×10-6. On the basis of summarizing geological characteristics and genetic model of the Guandonggou copper polymetallic deposit, combined with the characteristics of regional typical deposits, we summarizes the ore bearing strata, magmatic rocks, structures and other metallogenic geological constraints, so as to provide prospecting direction for copper polymetallic deposits in the Chifeng area. |
