阿木内格山东段钾长石矿床是青海省最重要的钾长石矿产地之一，矿体主要产于海西期的钾长伟晶岩脉中，古元古代达肯大坂（岩）群中部的碳酸盐组合为其赋矿围岩，区内共查明钾长伟晶岩脉有近百条，其中1号、206号为规模最大的伟晶岩脉，钾长石矿资源量丰富。文章在系统阐述区域成矿地质背景、矿区地质特征及矿床地质特征的基础上，并对其矿床成因进行了分析探讨。

The potassium feldspar deposit in eastern AMuneige mountain is one of the most important potash feldspar mines in Qing-hai province, which ore body is mainly produced in potassium feldspar pegmatite vein of hercynian period, and its wall -rocks is Carbonate combination,which consist in the middle part of Paleoproterozoic Dak-endaban Group.It has found out nearly one hundred potassium feldspar pegmatite vein,and the no. 1, no. 206 are the largest pegmatite veins, which is rich in resources. Based on regional geological background 、mining area geological features and geologic features of the orebody, the article analyses the reasons of the deposits.
