The Metallogenic Characteristics And Prospecting Potential Of The Fe Polymctallic Deposits In Zharigen Area, Qinghai

Zarigen area is located in the northwest edge of the Qiangtang land mass andbelongs to the Kaixinling-Zaduo late Paleozoic to Mesozoic arc basin system intectonics. Meanwhile this area is situated in the intersection of the Tuotuohe-Zaduo,the Wuli—Nangqian, and Danrong-Dongba metallogenic belts. The Tuotuohe-Zaduometallogenic belt are early Paleozoic and Himalayan, which is composed of Cu, Mu,Pb, Zn (Rare element Rare earth Au, Ag), Lake Salt, Glauber’s salt, Limestone, andCoal. Mainly include minerals have been discovered in the region Fe,Pb, Zn,Cu,barite, gypsum, coal al. The main production in iron ore in Basic volcanic rocks ofNuoribagaribao. Belongs to volcanic type spray flow deposits.Pb Zn Mineralization isrelated to tertiary large-scale thrust nappe action of the product of hydrothermalactivity.Cu Mineralization of ore-forming process is more complicated.hydrothermaltype, volcanic jet deposition type, etc. Barite ore into hydrothermal type. Gypsum andcoal into sedimentary type.It analyze the regional geological background by the formation、magmatic rock、structure、 Geophysical and Geochemical Exploration.The Pb Zn deposit ofNuoribanabao,represented by the hot water flow sedimentary type deposit（VMS）and Pb Zn depositp of Kongjie represented by the low temperature hydrothermal typedeposit to metallogenic model is given priority. the ore-controlling factors,the genesis,the metallogenic regularities, the metallogenic models and prospecting direction ofthe Copper-Lead-Zinc polymetallic deposits in this area, and puts forward aprospecting direction, which guides the next step of exploration work.
