摘要
轧轧龙铅锌矿地处西藏冈底斯Cu、Mo、Pb、Zn、Au、Fe成矿带中段。本文在详细研究矿体特征和控矿因素基础上,总结了成矿规律,明确了找矿标志。铅锌矿体严格受断层破碎带控制,多呈脉状、似层状、豆荚状、透镜体状。断裂构造为成矿热液提供了导矿通道,亦是主要的储矿空间。矿区岩浆岩为成矿提供了主要物质来源以及气—液热源和热驱动力。矿石矿物以方铅矿、闪锌矿为主,其次为黄铜矿、黄铁矿。研究认为,矿床成因属构造热液充填型多金属矿。
The Zhazhalong Pb-Zn deposit lies in the middle section of the GangdisêCu-Mo-Pb-Zn-Au-Fe metallogenic belt.The Pb-Zn orebodies occur in veined,stratoid,pod-like,lenticular form and are controlled by fault and fractured zone.Ore minerals are galena,sphalerite,secondly,chalcopyrite and pyrite.Faulted structure acted as both ore fluid channel and host structure.Ore fluids were derived from magmatic rock.The deposit belongs to structure-hydrothermal filling deposit.
