摘要
新疆塔木—卡兰古铅锌矿带矿床属于台缘碳酸盐岩容矿的超低温热液成因。矿床赋存于中泥盆统—下石炭统 3个控矿的由碎屑岩与碳酸盐岩组成的古含水层中。角砾岩、矿体均具有复杂的产状。影响矿体产出的主要因素包括碎屑岩 -碳酸盐岩界面、构造、低温热液交代作用以及容矿围岩的岩性。铅锌、铜、铁矿均是统一的成矿系统的一部分 ,锌 (铅 )矿围岩以碳酸盐岩为主 ,铜矿围岩为紫红色碎屑岩 ,铅矿围岩为灰白色碎屑岩。各主要矿床深部及外围均存在较好的找矿前景。
The lead-zinc deposits occur in the margin carbonate rocks, formed from low temperature hydrothermal. The deposits are located in three paleoaquifer that consist of sandstone and overlying carbonate rocks. Ore-bodies are all found in the breccia-rocks which contain lead-zinc minerals, and the ore-bodies and breccia-rocks are of complex shape, and occurred as no regular. The rich bodies are often found in the middle of breccia-rock. The major factor affecting the shape of ore-body are the interface between sandstone and carbonate rocks, faults, alterated by low temperature hydrothermal, and the property of wall-rocks. The lead-zinc, copper and iron mineralizations in this area are all in one ore-forming system. The wall-rock of zinc(lead) deposits mostly is carbonate rocks, that of copper is amaranth sandstone and carbonate rocks, and that of lead is grey sandstone. The studies on the ore deposits geology show that there are enormous exploring foreground in this area and in the deep of deposits.
