摘　　要：亚桂拉矿区位于晚古生代-中生代冈底斯-喜马拉雅构造区北中部的念青唐古拉地区,区内赋矿层位为上石炭-下二叠统来姑组第二岩性段(C_2P_1l^2),并严格受地层、岩性及近东西向断层破碎带控制。区域内可见属于燕山晚期的黑云母花岗岩(γ53)分布,成矿物质来源于该花岗岩。矿体的分布受矿区内三条走向近平行的断层控制。本文通过介绍该地区区域地质背景及矿床地质特征,分析总结该类矿床的找矿标志,为寻找相同成因的同种类型矿床提供理论找矿依据。The Yaguila mining area is located in Nyenchen tanglha region which is in the north central of the mountain-Himalayan tectonic zone, late Paleozoic-Mesozoic. The ore-bearing stratum in the area is the second section of Laigu formation, upper carboniferous-Lower Permian（C2P1l2）,and strictly controlled by strata, lithology and fault fracture zone of nearly east-west. There is biotite granite （γ53） in visible area which belongs to late yanshanian and ore-forming material comes from it. The distribution of the ore bodies were controlled by three faults close to parallel. In this paper, through the introduction to the regional geological background and geological characteristics of deposit, we can conclude the ore-prospecting evidence to provide theoretical basis for looking for the same type deposit next.
