中文摘要:
      乌拉根铅锌矿为层控型矿床,主要受控于下白垩统克孜勒苏群(K1kz),经勘探证实具有超大型资源潜力。赋矿层位及岩性为下白垩统克孜勒苏群顶部第五岩性段(K1kz5)灰白色砂砾岩和古近系阿尔塔什组(E1a)底部坍塌角砾岩,具有强烈的层控特性;辫状河三角洲相沉积的下白垩统克孜勒苏群第五岩性段(K1kz5)灰白色块状砂砾岩,形成了原始矿源层;大规模盆地卤水(油田卤水)是造成铅锌矿的迁移与富集的主要因素;活动的断裂构造以及断裂破碎带为萃取深部成矿物质、含矿热卤水的形成以及循环提供了通道,形成局部的铅锌矿富矿体;氧化淋滤作用造成Pb、Zn的迁移和一定深度氧化矿的形成,是局部铅锌矿富集的主要成因。
英文摘要:
      Wulagen lead-zinc deposit is a stratabound deposit, and is mainly controlled by the Lower Cretaceous Kizilsu group(K1kz); It is proved that it has a resource potential of superlarge scale deposit by detailed exploration. The ore-bearing horizon and lithology is offwhite glutenites, which belongs to 5th lithologic member of Kizilsu group in Lower Cretaceous (K1kz5) , and collapse breccias in bottom of Altash formation in Paleogene (E1a) .The deposit has a strong stratabound features;The offwhite massive glutenites of 5th lithologic member of Kizilsu group in Lower Cretaceous , which formed the original source, were covered by braided river delta island phase sediments ; large-scale basin brine (oilfield brine) is the main factor of the migration and enrichment of lead and zinc; active faults and fracture zones provide a channel to extract ore-forming material in depth, form and cycle the ore-bearing brine, which locally form lead-zinc oreshoots; oxidative leaching cause the migration of Pb and Zn and the formation of a certain depth oxidized ore, which is the main cause of local lead and zinc enrichment.
