西藏蒙亚啊铅锌矿区地质成矿机理浅析

A brief analysis of the geological metallogenic mechanism of the mengya lead-zinc mine in Tibet

西藏蒙亚啊铅锌矿区成矿与地层、岩浆岩、构造关系密切。矿区洛巴堆组、来姑组三段和来姑组二段为含矿地层。蒙亚啊矿区发生了一系列的推覆构造运动以及强烈的岩浆事件,控制了矿区矿体的产出状态。同时在这些构造破碎带受外动力的剥蚀,形成了蒙亚啊负地貌成矿的特点。

The metallogenic relationship is closely related to stratum,magmatic rock and structure in the mengya lead-zinc mine in Tibet.The ore-bearing strata are loba-dui group,laigu group and laigu group.A series of nappe tectonics and strong magmatic events occurred in the mengya mining area,which controlled the production state of the ore body.At the same time,these tectonic fracture zones were denuded by exodynamic denudation,which formed the characteristics of monya-ah negative geomorphologic mineralization.
