The post-collisional magmatism of Qiman Tagh is characterized by the intrusion of voluminous intermediate to felsic granitoids, including syenogranite, monzogranite, granodiorite, tonalite and diorite. The granitoids can be divided into two magmatic suites: Calc-alkaline (CA) and alkaline (Alk), which were emplaced from ~236Ma to ~204Ma. The CA sui...

: The Tuolugou cobalt deposit is the first independent large-scale Co- and Au-bearing deposit discovered in northwestern China. It is located in the eastern Kunlun orogenic belt in Qinghai Province, and occurs conformably in low-grade metamorphic volcano-sedimentary rock series with well-developed Na-rich hydrothermal sedimentary rocks and typical...
Article
Anatase and its allomorphic mineral rutile have the most prominent economic significance among titanium mineral resources and constitute one of the badly needed mineral resources currently in China. The Yantizishan‐Moshishan anatase deposit was formerly referred to as an iron deposit Based on recent investigation and exploration the authors believe...
Article
The Tanjianshan gold deposit, located at the tectonic boundary between the Oulongbuluk block (OB) and North Qaidam orogenic belt (NQO) on the northern margin of the Qaidam basin (NMQB), western China, underwent Early Palaeozoic and Late Palaeozoic to Early Mesozoic multiple accretions and collisional orogenies. It is a typical example of a deposit...
Article
Central Fujian Rift is another new and important volcanogenic massive sulfide Pb-Zn polymetallic metallogenetic belt. In order to find out the material genesis and mineralization period of Meixian-type Pb-Zn-Ag deposits, S and Pb isotope analysis and isotope geochronology of ores and wall rocks for five major deposits are discussed. It is concluded...
Conference Paper
The central Fujian rift is anew and important metallogenic province of volcanogenic massive sulfide deposits in China, where several large- and middle-size Pb-Zn deposits were recently discovered. All of the VMS deposits, here called Meixian-style, occur within Meso-NeoProterozoic greenschists that outcrop as metamorphic basement inliers and are ch...
Conference Paper
Xenoliths within augite diorite at the Chaihalanzi gold deposit are grouped into mafic and amphibolite compositions; the mafic ones have experienced granulite metamorphism. Geochemistry, P-T conditions and isotopes of the mafic xenoliths indicate that they were derived from the lower continental crust and resulted from magmatic underplating during...
Chapter
Alkaline skarns consist of special Na (K, Ca, Mg, Fe, Al) silicate matasomatic minerals, such as aegirine, aegirine-augite, sodic diopside, richterite, arfvedsonite, eckermannite, magnesio-arfvedsonite, sodic tremolite and phlogopite, and are typically associated with REE, Nb (Fe, U, Th) mineralization. They occur chiefly in the contact zones betwe...
Article
In this paper, the determination of the mined region and fire area in Zhangling coal field, Jincheng city, Shanxi province, China, is discussed. Through the description and analysis of the geologic characteristic of the region, the georadar characteristic of the mined region and the geothermal field distribution of the fire area, synthesizing drill...
