The East Kunlun metallogenic belt, located in the binding part between the south mobile belt of Xiyu block and South China block, belongs to the Kunlun suture belt of Qilian Qinling suture system. It consists of three regional deep seated faults trending from near EW to NWW in the south, middle and north of the Kunlun basin, and forms a complicated structure of this belt. Hence, three tectonic metallogenic units were divided: the north, middle and south belt of East Kunlun. All three fractures are the long lived regional deep fractures cutting through the earth's crust or lithosphere, which not only form the boundary of each geologic unit but control the distribution of magmatic rock, uplifting of East Kunlun, sedimentary basins and formation of depression zone. Along with secondary NW , NNW and NE trending faults, the three fractures cut strata of different era and some rock masses into fault blocks on various scales. Therefore, the fracture structures of different levels, which can be storage space for ore, provide excellent migration passages and occurrence space for formation of various ore deposits. The strata in the region were formed mainly in Precambrian, Ordovician Silurian, Carboniferous Permian, Triassic and Cenozoic Era. As for regional distribution, the outcrops in the middle and northern Kunlong belts are similar while there is significant difference between the south belt and other two belts. Magmatic activities were very strong and frequent, and are distributed extensively in fault uplift zone of the north slope of Kunlun Mountain as well as the Qimantage region, with the famous granite belt formed in the major ridge of Kunlun mountain and small amount of intermediate acid intrusive rocks exposed in the south slope. Lithological characters are shown as mafic, ultramafice and acid. The main active periods are Caledonian and Variscan, followed by Indosinian and Yanshanian, with minor mafic and ultramafic exhalative activities existing in Xingkai and Early Xingkai period. East Kunlun metallogenic belt is one of the most important metallogenic belts in Qinghai with advantageous geological conditions and great prospecting potential where structures of intrusive rock, fold and fracture are well developed as well as frequent and strong magmatic activities. Moreover, this belt is also the concentrated region of major industrial ore deposits in Qinghai with large reserves and high grade and concurrently paragenic and associated poly metallic deposit normally possess certain scale. In particularly most skarn type and sedimentary metamorphic iron ores are concentrated in this area. Genetic types of iron ore deposits in the East Kunlun metallogenic belt are complex, including exhalative sedimentary and pyrometasomatic metamorphism reformation type related to volcanic exhalative sedimentation, and sedimentary metamorphic and skarn types. Therefore, the belt is provided with metallogenic conditions for large or super large ore deposits. The ore deposits distribute mostly along the deep fractures of the north, middle and south of Kunlun Mountain and are closely connected with secondary structures and magmatic rock mass. The west of East Kunlun metallogenic belt is the important prospecting area for large ore deposits, the middle has prospecting potential of sedimentary metamorphic iron ores, and the east is regarded as the accumulation area of skarn type iron ore deposits. The resources of iron ores in this belt occupy 75.51% of the whole province and large quantity of useful components associated with iron deposits can be also utilized. The contact metasomatic iron deposits are the target for current exploration. The ores of this kind is excellent and the grade of TFe is between 35% and 55%, with low contents of sulphur and phosphorus (normally lower than industrial requirements). Especially in the Dulan and Yemaquan areas, the associated elements in iron depsotis, such as such as lead, zinc, copper, gold, silver, tin, cobalt, bismuth, cadmium, pyrite, etc. can be utilized, which greatly improves the development value.
