新疆塔木—卡兰古铅锌矿带位于塔里木板块西南缘之晚古生代碳酸盐台地环境中。矿化以铅锌矿为主 ,个别矿床含铜。矿床赋存于中泥盆统—下石炭统三个控矿的古含水层中 ,矿体形态复杂 ,富矿段往往赋存于多组断裂构造交汇部位。矿石根据其结构大体可分两类 :一类呈角砾状构造 ,硫化物呈浸染状 ,共 (伴 )生赤铁矿和磁铁矿 ;另一类矿石中硫化物以胶状、草莓状结构为主。硫化物硫同位素值具有较宽的范围 ,δ3 4 S为 - 39.2‰～ + 14‰ ,主要集中在 - 2 9.3‰～- 17.7‰和 - 3.6‰～ + 5 .1‰两个区间 ,分别与上述两类矿石相对应。研究表明 ,位于泥盆系与石炭系间的第二古含水层是最重要的找矿层位 ,角砾岩带是重要的找矿评价标志 ,矿床成因可能属密西西比河谷型 (MVT) ,两种性质差异很大的低温热液混合引起成矿物质的沉淀和成矿
The Tarim-Kalanchu lead-zinc ore belt in Xinjiang is located in the Late Paleozoic carbonate platform environment on the southwestern margin of the Tarim plate. Mineralization is mainly lead-zinc mine, individual deposits contain copper. The ore deposits occur in the three Ordovician-controlled paleo-aquifers of the Middle Devonian-Lower Carboniferous. The ore bodies are complex in shape, and the ore-rich sections tend to occur in the intersections of multiple fault structures. According to its structure, ore can be roughly divided into two types: one is brecciated structure, the sulfide is disseminated, co-(with) raw hematite and magnetite; the other type of sulfide minerals to gelatinous, Structure-based. Sulfur sulfide isotope values have a wide range of δ3 4 S of - 39.2 ‰ ~ + 14 ‰, mainly concentrated in the -2 9.3 ‰ - 17.7 ‰ and - 3.6 ‰ ~ +5 .1 ‰ two intervals, respectively The two types of ore corresponding. The study shows that the second paleo-aquifer located between the Devonian and Carboniferous is the most important ore-prospecting level. Breccia belt is an important indicator for ore prospecting. The genesis of the deposit may be the MVT (Mississippi Valley Type) Low-temperature hydrothermal mixing with very different properties causes precipitation and mineralization of ore-forming materials
