摘要

矿区位于Variscan期形成的齐达曼塔格—都兰多金属成矿带西段,含钴、铋、铜、铅、锌,是成矿有利地段。矿区主要出露地层为下元古代形成的金水口群下岩群,主要岩性组合为混合石化片麻岩与大理岩、夕卡岩。矽卡岩是本区主要的含矿岩性。通过对细查区(矿群I)的钻井工程控制,圈定了17个铁矿体,长度200-1500m,倾斜延伸100-400m,矿体厚度1-10m,埋深200-400m。从本区勘查成果看,矿区深部矿体规模大,找矿前景好。

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