| The Kunlun nephritis divide into South and North metallogenic belt with ridge ofShasong ulla. South metallogenic belt located in south of main ridge of Shasongulla,white jade-based, output in Upper Proterozoic Wanbaogou carbonate group;North metallogenic belt located in north of ridge Shasong ulla, sapphire-based, outputin Proterozoic Jinshuikou group. The location of the study area are Northmetallogenic belt of Kunlun nephritis.The study area has lower degree of geological work, mostly are in small-scale on thebasis of geological work, jade ore prospecting work begin after Golmud CitySanchahe the Kunlun jade mine discovered,only expand year by year. The systemdata is relatively scarce. However, a comprehensive study on the region, researchrelatively large,improve its degree of geological work.This thesis is based on a project of Golmud City, Qinghai Province, FuKunshan jademine project, based on professional knowledge, on the basis of comprehensiveanalysis and study the area latest physical and chemical data, the implementation ofresearch projects to the geology of the area identified in the geological record,physical specimen, sample test analysis as a basis for research. Written in the papersfocus on a summary of the actual phenomena, without a theoretical illusion andprediction.Combining former the basis of geological work and investigation of jade mines,generally identified geological background of regional jade mine, the mainore-controlling factors and type of mineralization; has a general knowledge ofrelations of intrusive rocks, structure, stratigraphy and jade mineralization andcharacteristics of jade mine (of) body shape, size, occurrence, quality basic.The thejade mineralization. closely related of Variscan intermediate-acidic intrusive rocksand Proterozoic Jinshuikou group magnesia marble. |
