摘要
对塔卡提铅锌矿形成的地质背景、矿区地质特征、成矿机制和成矿远景进行了初步分析.结果表明:塔卡提铅锌矿床位于西昆仑塔木-卡兰古铅锌铜成矿构造带的远景区,区域上受西昆仑构造带和康西瓦构造带共同控制.矿体产出部位严格受白云岩-砂岩接触层位及构造破碎带控制,矿体呈层状或脉状;围岩主要为蚀变白云岩、碎屑砂岩;主要矿石矿物为方铅矿和闪锌矿;矿床类型与密西西比河谷型矿床类似.由于矿床处于西昆仑塔木-卡兰古铅锌铜成矿构造带的远景区,铅锌矿床潜在资源量较大,同时区域上相同类型铅锌矿床较多,具有较好的成矿远景.
The geological settings, geological characteristics, metallogenic and ore potentialities of the Takati lead-zinc deposit were discussed. The Takati lead-zinc deposit is located in the potentiality zone of the Tamu- Kalangu Pb-Zn-Cu ore belt in west Kunlun and is controlled by the west Kunlun tectonic belt and Kangxiwa tectonic belt. The orebodies occur in the strata or the vein. The orehodies are controlled by the dolomite sandstone exposed layer and the inter-formational zones. Wall rock is made up of altered dolostone and clastic sandstone. The ore minerals include galena and sphalerite and the ore types are similar to MVT. The potential resources are huge, especially for lead-zinc deposit. So the potentiality of ore is great.
