The Geological Characteristics And Prospecting Direction Of The Former Bayan Molybdenum Mine Of Mongolia

QianBayan molybdenum mine located in Mongolia Sukhbaatar province Middletownamount Chagan County, Inner Mongolia Autonomous Region and China XilinhotDongwuzhumuqinqi west. Located within the area of the Southern Mongolian Paleozoicorogenic belt south of the huge arc structure, the North China platform and between theSiberian plate. By the North China Craton, the ancient oceanic crust Mongolia and Siberia,multi-stage plate subduction, collision and docking role of influence within the area rangePaleozoic-widely distributed sedimentary rocks, deep fault zone (layer) criss-crossing allkinds of intrusive rocks are well developed, number of metal deposits (dot) many, as theCentral Asian giant orogenic belt and metal mineralization important part. Area exposedstrata simple, Ordovician and Silurian-Devonian, Carboniferous, Jurassic, Cretaceous, LateTertiary-Quaternary. Part Nukuteda class penthouse on the tectonic anticline belong.Regional mineralized zone along Nukuteda Ban penthouse anticline distribution hub,obviously its control. Mineralization is mainly produced in the late Paleozoic and Mesozoicintrusive rocks in the Late Paleozoic and Mesozoic tectonic and magmatic mineralization hasa close relationship with. In addition, according to the relevant metallogenic theory, theregion mineralized belt W, Sn, Mo, Bi, Be, Ta, Cu, Pb, Zn, Au and fluorite mineralization isactually an acidic intrusive rocks with a genetic relationship by the high temperature to lowtemperature metallogenic series, in which mineralization series, W-Mo mineralization forthe area ’s main type. Former Bayan molybdenum is one of the types of deposits.Former Bayan Mo mineralization with the NE-SW trending, surface sporadic outcropsmineralized zone about800m, width400m. Rocks containing ore deposits are mainlysecondary Greisen and greisenized of coarse-grained granite and monzonite mineralizationand alteration of porphyritic monzonite granite. According ore ore-controlling structure andthe distribution range, can be divided into four orebodies. Ore body in the plane and thevertical columnar, large veins, lens-shaped echelon distribution. The main types of oredeposits of natural molybdenum greisen, Secondary Quartzite molybdenum, molybdenumaltered granite-type and broken belt type.Ore body in contact with the rock clear lines to clear, partly mutation relationshipbetween some of the gradient, a small part of the fault contact.Based on field observations veinlets interspersed between the relationship betweenmetallic minerals and mineral combinations. Deposits can be divided into two phases, theearly stages of an oxide, sulfide stage late as. Mineralization is the basic rule: In the Late Carboniferous porphyritic monzoniteintrusive granite after the regional role under the influence of the formation of NEE andNWW fracture. As early as the Middle Jurassic coarse-grained granite intrusive monzoniteand multiple regional tectonic influence, has formed nearly NEE silicification alterationzone, greisenized belt and greisen zone. Finally, in the center of the alteration zone and theintrusive contact zone composite rock, forming a disseminated ore veins.Former Pakistani Molybdenum Molybdenum is a sound related to granite veinlets a diptype high-temperature hydrothermal deposits, volcanic activity produced in the multi-phasedevelopment of intrusive rocks area by NEE much alteration zone of tectonic activity andintrusions touch screen dual control. The new generation of intrusion concealed rock,providing a source of ore-forming substance: the prototype of many active faults,hydrothermal mineralization opens up a channel migration and accumulation of space.For the former Pakistani tone through molybdenum molybdenum mine geology andmineralization regularity of research, reveals the common characteristics of such deposits bysimilar prospecting as a basis for seeking such deposits, from the point and the surface of theresearch, but also on further Bayan Mongol studies before mine geology and surroundingareas guiding role in regional mineral has certain characteristics.
