摘要：

青海省尕林格铁矿床位于东昆仑西段祁漫塔格弧后盆地中部。近年来通过新一轮地质勘查工作，该矿床铁资源／储量进一步的扩大。通过分析研究认为，朵林格矿床的铁矿体呈似层状、透镜状基本顺层产于一套奥陶纪滩间山群(OST)的火山-沉积岩中，矿体规模大，厚度基本稳定，其成矿地质背景和矿床地质特征表明，该矿床属火山喷流沉积一岩浆热液叠加改造型铁矿床。

Abstract:

Galinge iron deposit in Geermu city of Qinghai province is located at the middle part of Qimantage back - arc basin of the western segment in the eastern Kunlun Mt. The new investigation shows that the reserves of ore deposits is increased. The analyse thinking that the ore body presents to tier of shapes, the optical lens shape aways along tier which products in a set of the Tan jian shan group of ordovician (OST) in volcanic-sedimentary,rock, extends mole than kilometers, the result is gained from the characters of the geological setting, geological features and deposit scale that the ore belong to the volcanic exhalation sedimentation-magmatic and hydrothermal process super-imposion-reformation ore deposit.

Key words: Galinge, high-grade iron deposit, volcanic exhalation, superimposion-reformation, genesis of ore deposit
