| 中文摘要: |
| 低山头多金属矿位于青海格尔木市境内,属于伯喀里克—香日德印支期Au-Pb-Zn-Fe-Cu多金属成矿带,区内成矿地质背景条件良好,已圈出多金属矿(化)体9处,组成5条含矿蚀变带,文章着重介绍Ⅳ号含矿蚀变带。研究表明:Ⅳ号含矿蚀变带受北西—南东向断裂破碎带控制明显,总体走向呈120°,圈定出Pb、Zn、Ag、In矿体4条；矿体呈带状、条带状、透镜状产出,硅化、高岭土化、碳酸盐化是该类矿体的重要的找矿标志；Ⅳ号含矿蚀变带的形成与印支期石英闪长玢岩侵入活动关系密切。 |
| 英文摘要: |
| Dishantou polymetallic ore is located in Geermu area of Qinghai Province, belonging to the Au-Pb-Zn-Fe-Cu polymetallic metallogenic belt of Kerala-fragrant Japanese Indochina period, and the Metallogenic geological background in the region In good condition, 9 parts of polymetallic ore (fluidized) have been circled, and 5 ore-bearing alteration bands have been formed, and the ore-bearing alteration zone of Ⅳ is emphatically introduced in this paper. The results show that the ore-bearing alteration zone of Ⅳ is controlled obviously by the North West-south East fault crushing zone, and the overall direction is 120°, and 4 articles of Pb, Zn, Ag and In orebody are identified, and the orebody is banded, striped and lenticular, and silica, kaolin and carbonate are important prospecting signs for this kind of orebody. The formation of the ore-bearing alteration zone of the Ⅳ is closely related to the invasive activity of the late diorite in Indochina. |
