| 中文摘要: |
| 托帕铅锌铜矿位于喀什坳陷北部的塔什皮萨克复背斜内,矿体呈层状、似层状赋存于下白垩统克孜勒苏群第三岩性段(K1kz3)灰白色砂砾岩和始新统卡拉塔尔组(E2k)底部的坍塌角砾岩及下白垩统克孜勒苏群第一岩性段(K1kz1)灰白色砂岩中。成矿的原始矿源层、盆地卤水改造及后期构造热液叠加等成矿期次和成矿作用与乌拉根铅锌矿相似,但含矿层位不同,经历的后期改造较弱。今后找矿应以塔什皮萨克复背斜南部可能存在的K1kz5、E1a铅锌赋矿层位为重点,在盆地卤水改造、后期构造热液叠加强烈的地段进行。 |
| 英文摘要: |
| The Topaz lead-zinc-copper deposit is located in the Tashipisaac complex anticline in the northern Kashi depression area. The lead-zinc-copper ore bodies occur in forms of layered and inter-bedded within the light grey sandstone and conglomerate of the 3rd lithologic member of Kezilesu group (K1kz3), sloughing breccia at the bottom of Eocene Kalataer formation (E2k) and grey white sandstone of the first lithologic member of Kezilesu group (K1kz1) of Lower Cretaceous system. The ore-bearing sources, transformation of basin brine fluid and the mineralization stages and process by the later tectonic and hydrothermal superposition in the deposit area are similar to the Wulagen lead and zinc deposit in the region, however, there is a difference between these two deposits, i.e., the ore-bearing horizons are different, and the later deformation in the Topaz is weak. Based on the study, it is predicted that the exploration target in this area should focus on those areas where the ore-bearing horizons of K1kz and E1a occur in the syncline located in the southern Tashipisake complex anticline and intensely transformation of basin brine and the superposition of the later stage tectonic and hydrothermal transformation. |
