Abstract:
Binggounan area is located in Qimantage mineralization belt in the west section of East-Kunlun orogenic belt, Qinghai Province, with very favorable mineralization condition. But the prospecting type and prospecting potential are disclear in this area, because the related depositsare discovered very late and the degree of geological works is low. After analyzing the geological characteristics of the related deposits, metallogenic regularity, and the data of geophysical and geochemical survey, the following results have been achieved by combining with the recent prospecting discoveries of copper-nickel ore. The mineralization types are divides as five types:skarn type, hydrothermal type, porphyry type, magmatic liquation type and sedimentary metamorphism type. The skarn-hydrothermal-porphyry Cu-Pb-Zn-Mo deposit and magmatic liquation Ni-Cu-Co deposit are the most important metallogenic series in this area. The former is closely related to Late Triassic granitic magmatism, but the latteris closely related to mantle magmatic activity that occurred in the post-collision extensional tectonic setting.The prospecting potential in Binggounan area is analyzed by using the "Preferenceore-forming prediction".The results suggest that, the prospecting potential of hydrothermal type Pb-Zn-Cu deposit is huge respectively in the north part of No. Ⅲ mine belt, and the ones of magmatic liquation Ni-Cu-Co depositis good in the middle-north part of this mining area.
