The Chang'an gold deposit, Yunnan province is one of five large deposits in the Ailaoshan belt that most important ore Sanjiang Tethyan metallogenic domain. Geochemical study pyrite deposit was conducted using laser ablation inductively coupled plasma mass spectroscopy. Three types hydrothermal were identified ores and wall rocks, i.e., coarse euhedral crystals syenite (Py1), grains disseminated altered sandstones or sandstone (Py2), fine-grained (Py3). Their trace elements exhibit different...
The Tongling ore district of the Middle-Lower Yangtze metallogenic belt is a famous Cu-Au-Fe-S polymetal region, and its tectonic deformation, magmatic evolution, processes have been studied for decades. In this article, we propose comprehensive tectonic-magmatic-metallogenic model ore-forming mechanism constrained by magmatism regional deformation. district, regime underwent two transitions. (1) Middle Triassic, transitioned from quiescence to intense compression. During contraction,...
The geochemical maps and anomaly produced based on the data in databases of Regional Geochemistry–National Reconnaissance (RGNR) National Multipurpose Geochemistry Survey (NMPRGS) projects have played a crucial role China’s exploration. A survey Mojiang area, Yunnan Province, China, has been completed reveals potential new regions for Ni exploration related to occurrences serpentinite melanges. need be drawn this area. Traditional maps, heavily dependent quantity, are less suitable...
The Special Issue ‘New Advances and Illustrations in Applied Geochemistry China’ was organized for the presentation of ideas from 9th National Conference on China held Chengdu, Sichuan Province, October 2023 [...]
Abstract The Dayingezhuang gold deposit is located in the central part of Zhaoping Fault Zone, which one most important gold‐hosting faults Jiaodong province China. a typical large‐scale shear zone‐hosted disseminated with superimposed silver mineralization. Fluid inclusion (FI) petrography and microthermometry, analysis oxygen hydrogen isotopes for fluid inclusions were conducted to determine characteristics ore‐forming fluids processes Microthermometry data FI indicated that are...
Abstract The Shangzhuang altered‐rock type gold ore deposit is located in the middle segment of and controlled by Wang'ershan fault zone northwestern part Jiaodong province, China. deformation evolution, structure strain stress fields its ore‐controlling effect are discussed this paper. It revealed that evolution has mainly undergone four phases: early ductile deformation, second NE‐striking horizontal simple shear, third compression‐shear final NW‐striking compression. mineralization...
Geochemical maps play an important role in mineral resource exploration. There are three traditional methods for creating geochemical maps: the cumulative frequency method, logarithmic interval and Avg±k∗Std (where Avg Std abbreviations of average standard deviation, k is a multiple Std) method. However, with increasing scope study area data, limitations methods, which depend on amount exposed. A fixed-value method Sn geological mapping proposed to overcome methods. In concentrations divided...
Abstract A series of element concentrations sampled from four drill cores with a length about 1000 m into different skarn‐type deposits were selected the Shizishan orefield, central Tongling, southeastern part Anhui Province. Using multifractal method, distribution and migration characteristics major trace elements are analyzed. The spectrum is left‐skewed, whereas right‐skewed, which shows that in process skarn formation, enriched only locally, transported within much larger range....
With the explosive growth in demand for lithium (Li) resources, Mufushan area has been a hotspot Li deposit exploration China recent years. Geochemical maps and geochemical anomaly are basic of mineral resources. A fixed-value method to contour map is presented here, which concentrations divided into 19 levels on 18 fixed values, ranging from 5 μg/g (corresponding detection limit) 1858 cut-off grade hard-rock type) illustrated six color tones corresponding areas low background, high anomaly,...
