The census area is located about 350 kilometers west of Golmud City, with convenient transportation. The strata closely related to mineralization in the mining area mainly include Mesoproterozoic Langyashan Formation, Cambrian-Ordovician Tanjianshan Formation and Carboniferous Diosu Formation, and magmatic rocks mainly include Indosinian adamellite and potash feldspar granite.
From June 5438+February 2005 to June 5438+2+May 2065, the Third Institute of Geology and Mineral Exploration of Qinghai Province carried out exploration work. The exploration mineral is a polymetallic mine, the work level is general survey, and the investment is 83.08 million yuan.
(2) Description of results
In the work area, 20 1 1 mainly makes a detailed survey of the ⅵ ore belt according to the grid of 100 m× 80 m, and makes a general survey of the ⅱ ore belt, C6 magnetic anomaly, C7 magnetic anomaly and VIII ore belt. Preliminary estimate of 20 1 1 new (332+) ore belt. Metal mineralization mainly includes sphalerite, galena, chalcopyrite, pyrite, malachite, sphalerite and lead alum. Due to the superimposed transformation of hydrothermal solution in the later stage, the enrichment degree of local polymetallic mineralization is different. The types of ores are simple, including copper ore, zinc ore, zinc-iron ore, zinc-lead ore, zinc-lead copper ore and so on.
(3) the brief process of achievement
From 2005 to 2008, only the ⅱ ore belt with good outcrop was controlled and verified, but since 2009, the project team relied on excavators to increase the construction depth (up to 9 meters), and as a result, high-grade thick ore bodies were discovered, with good prospecting effect. From 2009 to 20 10, 26 low-slow magnetic anomalies were delineated in this area through high-precision magnetic survey of 1∶ 10000 and geological survey of 1∶ 10000. After verifying the low and slow magnetic anomalies, several polymetallic deposits were found in many places.
