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
