Prospect Evaluation of the Ore Cluster I of Qunli Iron Mine in Golmud, Qinghai Province, China

Abstract

The mining area is located in the western section of the Qitamantag--Dulan polymetallic metallogenic belt formed in the Variscan period, with cobalt, bismuth, copper, lead and zinc, and thus it is a favorable mineralization section. The main exposed stratum in the mining area is the lower rock group of the Jinshuikou Group formed in the lower proterozoic, and the main lithological combination is mixed petrified gneiss with marble and skarn. Skarn is the main ore-bearing lithology in the area. Through the drilling engineering control of the minutely investigated area (Ore Cluster I), 17 iron ore bodies are delineated, with a length of 200-1500m, an inclined extension of 100-400m, an ore body thickness of 1-10m, and a burial depth of 200-400m. Judging from the exploration results of this area, the deep ore body in the mining area is large in scale and good in the prospecting prospect.
