Attribution deposit of molybdenum and tungsten mineralization in the circum-Pacific belt, western copper in Sanjiang region - - molybdenum, molybdenum - molybdenum, copper molybdenum deposit in eastern China's membership in the Sanjiang fold system of copper - molybdenum mineralization belt (an ancient Mediterranean metallogenic belt) . According to the relationship and molybdenum deposits and mineralization characteristics of tectonic units of the eastern Pacific Rim molybdenum mineralization with mineralization is further divided into four provinces: ① DPRK paraplatform molybdenum mineralization Province; ② Northeast Hercynian fold system of copper - molybdenum mineralization Province; ③ Yangtze paraplatform copper - molybdenum mineralization Province; ④ South China fold system tungsten - copper - molybdenum mineralization province. One of the most striking is the Sino-Korean paraplatform molybdenum mineralization Province. 

 

It has been ascertained that the northern margin of the molybdenum mineralization Yanliao South East Qinling molybdenum belt edge, is the most important of the two molybdenum belt, which accounts for over 60% of the country's proven reserves of molybdenum industry, especially East Qinling molybdenum belt, molybdenum ore reserves of 3.6 million total t, total molybdenum (tungsten) deposit (points) 46, where large deposits 4: Jinduicheng molybdenum Mine, Shangfanggou (iron) ore, South mud Lake molybdenum (tungsten) ore, three village molybdenum (tungsten) ore; large deposits 4: big gully molybdenum (rhenium) mine, Shijiawan molybdenum, tungsten, molybdenum Yechangping ore, molybdenum ore Leimengou; medium deposit are: urd molybdenum and tungsten ore, silver Ravine molybdenum, copper and molybdenum mine QIUSHUWAN so. District-level control things have meaning to the structure; combine different tectonic systems, controls the distribution of composite parts and belt rock group, with a secondary control sense, metallogenic belt of large mine fields or mines, are in Neocathaysian or curved structure with zonal structure miter superimposed parts, like Jinduicheng, Huanglongpu zonal structure, such as mining in the east wing of composite parts with arc-shaped structure before HE Qi Lu Shan, luanchuan Nannihu ore field in zonal structure and barberry - Dabie arcuate structure superimposed parts; low-order sub-structure changes or transfer of composite structural parts, controls a small rock or ore, with three control significance. 

 

Indo western Sanjiang fold system of copper - molybdenum mineralization belt. Along deep faults in the area - a strong magmatic activity, Yanshan - Himalayan early acidic magmatic activity is frequent in the formation of the Himalayan Yulong porphyry copper (molybdenum) porphyry deposit and Machangqing - skarn molybdenum (copper) deposits. 

 

Mineralization age molybdenum deposit, for the purposes of the world, mainly Mesozoic and Cenozoic, molybdenum deposits formed during the two world accounting for about 90% of proven reserves total molybdenum. Except for a few of copper (molybdenum) deposits formed in the outer Hercynian Paleozoic and Cenozoic Himalayan, the vast majority of molybdenum deposits and copper (molybdenum) deposits are the product of the Mesozoic Yanshan period, which is due to the vast area of the eastern Yanshan faults and granitoid intrusions caused extensive development.
