| 摘 要： | 纳多弄铅锌矿床位于达拉克冈底斯弧盆系之那曲-洛隆弧前盆地，矿区出露的地层主要为上三叠统孟阿雄群（T3m），岩性主要为结晶灰岩、白云质灰岩。该矿床受地层、岩性以及断裂构造带的控制，其中盂阿雄群（T3m）是该矿床的含矿地层，矿体主要产于构造破碎带中。本文通过介绍了区域地质背景、矿区地质特征及成矿演化，初步分析了纳多弄铅锌矿床的成因。建立了成矿模式，认为该矿床属于层控碳酸盐岩热液脉型矿床。

| Abstract: | Na Duonong pb-zn deposit is located in Naqu-Luolong fore-arc basin of D-a Lake Gangdise lead-zinc-arc basin system.The strata exposed in the main mining area belongs to the Meng Axiong group of the Upper Triassic(T3 m),and mainly are crystalline limestone rocks and dolomitic limestones.This deposit is controlled by the strata,lithology and tectonic fracture zone.The ore body is mainly deposited in the fracture zone and it's ore-bearing strata is Meng Axiong group.Based on the introduction of the regional ge... |
