| description | Chelugoubei Gold Deposit in Yumen City, Gansu Province is located at the intersection of the western North Qilian Orogenic Belts and eastern Altyn Tagh Sinistral strike-slip fault shearing zones, which is a famous "golden triangle" in Northwest China. The formation of the deposit is closely related to the left-side Altyn fault shearing zone and the output is controlled by the secondary branch fault zone. The Paleozoic stratum is the main source layer of the mine, which is generally high in gold content in the region. The regional magmatic activity is strong and closely associated with the gold (mineralization) body. The Chelugou granodiorite complex provides heat source and part mine source for the deposit. Combined with the regional metallogenic background and using the method of comprehensive analogy of regional deposits, the authors compared the ore-controlling factors, such as strata structure magmatic rock physicochemical remote anomaly characteristics, as well as ore bodies, ores surrounding rock alteration and other geological characteristics of the deposits in detail, including Chelugoubei Gold Deposit, Hanshan Deposit, Yingzuishan Deposit, Dishuishan Deposit and other "gold triangle" deposits. It can be concluded that the Chellugoubei Gold Deposit has similar ore-controlling factors and very similar geological characteristics with the above-mentioned gold deposits. As an extension of the "Golden Triangle" gold belt in the Northeast China, it has the potential of concealed large-scale deep deposit. On this basis, the prospecting model of "Golden Triangle" gold deposits is further systematically summarized, and the prospecting criteria and prospecting direction have been discussed. The research result can provide some enlightenment for the further exploration of tectonic altered rock type gold deposit in this area and the North Qilian area. |
