Iron and copper mineralization in the Yueshan ore field is intricately linked to the Cretaceous Yueshan diorite intrusions, yet they frequently materialize as distinct deposits. Despite this, the key factors dictating the segregation of these metals remain poorly understood. To gain insights into the role of magma physicochemical conditions in this...

Global Cobalt (Co) is mainly mined from sediment-hosted, magmatic sulfide, or laterite deposits, but rarely in skarns. The Middle-Lower Yangtze River Valley Metallogenic Belt (MLYB), eastern China, is an important skarn iron ore producer, where skarn iron deposits are often associated with Co. The Zhuchong iron deposit is a typical high-grade skarn...

The Mo deposits in the Kunlun-Qinling-Dabie orogen are mainly associated with porphyry or porphyry-skarn mineralisation in a collision or post-collision setting. However, collision-type Mo deposits that are related to granite and mineralization produced in magmatic systems remain poorly constrained. To better define the genetic relationship between...

The East Kunlun orogenic belt (EKOB) is located in the northeastern part of the Qinghai-Tibetan Plateau, China. Voluminous Silurian-Devonian granitoids were formed during the Proto-Tethys Ocean subduction and collision process. In this study, zircon U-Pb age dating, in-situ Hf isotope analyses, and whole rock major and trace element analyses have b...

Abundant granitoids are exposed along the East Kunlun orogenic belt (EKOB), and many skarn deposits occur at the contacts between intrusions and strata. One such is the Xiaowolong deposit, a skarn-type tin polymetallic deposit that is temporally and spatially associated with porphyry monzogranite. Tin mineralization is mainly hosted by the skarn. I...

The Reshui porphyry Mo deposit is located in the East Kunlun orogenic belt (EKOB). Molybdenum mineralization is distributed in monzogranite and porphyritic monzogranite rocks, mainly presenting as various types of hydrothermal veinlets in altered wall rocks, and the orebodies are controlled by three groups of fractures. In this paper, we present th...

The Shuangkoushan quartz-syenite is situated in the west segment of Northern Qaidam. This paper reports results of LA-ICP-MS zircon U-Pb dating, whole-rock geochemical and Sr-Nd isotopic analyses of the quartz syenite. Geochemically, the Shuangkoushan quartz-syenite shows enrichment in silicon (SiO2 = 59.47% – 68.66%) and total alkali (Na2O + K2O =...

The magmatic Ni-Cu- (PGE) sulfide deposit is one of most important Copper-Nickel deposit types. It is of great significance to discussion about the metallogenic environment, mineralization and genetic mechanism of the type deposit. This paper has made a detailed analysis the Ni-Cu- (PGE) sulfide deposits on the conent of temporal and spatial distri...

In order to probe the genesis and tectonic significance of the granite in the Reshui area, geoehronologicai and geochemical studies of the Reshui monzogranite have been carried out in this paper. The results show that the Reshui monzogranite has LA-1CP-MS zircon U-Pb age of 231 ±1 Ma, indicating that it was formed in late Triassic. It has high cont...

The Xinghai-Zeku area of western China is one of the most important Au polymetallic metallogenic belts in Qinghai Province, China. To guide the mineral exploration in this area, log and isometric log-ratio (ilr) transformations of stream sediment data are evaluated using principal component analysis (PCA) combined with geological data to study the...

The Reshui Mo polymetallic deposit is located at the North Kunlun magmatic arc, where lots of intrusive rocks occur. Geochemical data reveal that the porphyroid biotite monzogranite from East Kunlun is rich in silicon (67.64%- 71.09%), A12O3 (13.8%-14.57%), Na20 (2.23%-3.02%), and K2O (3.95%-5.18%), with ratios of K2O/Na2O being 1.35-2.32 and A/CNK...
