The thermodynamics of electrochemical and complexation reactions involving the heterobimetallic triple-stranded helicates [MA(L5)3]n+ (M=Ru(II), Cr(III) and A=Ca(II), Lu(III)) reveal that solvation processes mask intramolecular intermetallic repulsions in solution, a phenomenon at the origin of the surprising stabilities of highly charged self-assembled polymetallic complexes in solution. A jud...
The medium-sized Songjianghe Au deposit is located in the southeastern part of Jiapigou-Haigou gold belt (JHGB) central eastern Jilin Province, NE China. mineralization primarily characterized by disseminated-style ores and hosted low-/medium-grade metamorphic rocks Seluohe Group. ore bodies are governed NNW-striking brittle-ductile structures spatially correlated with silicic sericitic alterat...
Purpose. Study on the processes contributing to formation of pyrite-polymetallic mineralization in Rudny Altai, development recommendations for directions further research. Methodology. Analysis literature and fund materials, field studies within known ore fields deposits, sampling laboratory studies: spectral analysis, chemical composition host rocks (ISP-MS Agilent 7500cx), study mineral main...
To reveal the genesis of Makeng-style iron polymetallic deposits from SE China in paleo-Pacific tectonic domain, a new analytical method LA-ICPMS garnet U-Pb dating and rare Earth element analysis was conducted for Makeng, Luoyang, Dapai Pantian deposits. The results nine skarn samples these suggested that mainly formed during 137–130 Ma, which is consistent with zircon molybdenite Re-Os ages. ...
Antimony deposits contain little Sn, whereas Sb and Pb are not the principally contained metal of granite-related Sn deposits. The Danchi Sn-metallogenic ore belt (DSOB) in southwestern China is characterized by Sn-Sb-Zn-Pb co-enrichment, yet triggers poorly constrained. Beixiang deposit southern DSOB consists stage I Sn-Zn II Sb-Pb-Zn mineralization. Here, we analyzed cassiterite U-Pb age, flu...
Lanthanide ions possess fascinating optical properties and their discovery, first industrial uses and present high technological applications are largely governed by their interaction with light. Lighting devices (economical luminescent lamps, light emitting diodes), television and computer displays, optical fibres, optical amplifiers, lasers, as well as responsive luminescent stains for biomed...
The method of bi-dimensional empirical mode decomposition (BEMD) and the combined methods entropy weight–Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) were used decompose gravity–magnetic data evaluate targets in Luziyuan Pb–Zn–Fe polymetallic ore field surrounding areas. Three meaningful intrinsic function (BIMF) images obtained BEMD at different wavelengths, depic...
The Lower Yangtze River Belt (LYRB) is a well-known and important base area with regard to Cu polymetallic resources in China. Large deposits the LYRB are strongly associated Cretaceous adakitic rocks. However, petrogenesis of Early adakites temporal–genetic relationship mineralization still disputable. Dongguashan (DGS) deposit Tongling ore cluster one largest LYRB. DGS intrusion mainly compri...
In gold-endowed greenstone belts, ore bodies generally correspond to orogenic gold systems (OGS) formed during the main deformation stage that led craton stabilization (syntectonic period). Most OGS deposits postdate and locally overprint magmatic-hydrothermal systems, such as Au-Cu porphyry mostly magmatic (synvolcanic period) polymetallic intrusion-related (IRGS) of syntectonic period. Porphy...
The Nikuyeh district is located south of the Tarom-Hashtjin metallogenic province in Western Alborz. Oligo-Miocene subvolcanic intrusion and Mid-Eocene volcanic rocks with composition of dacite to andesite are main igneous settings associated with Nikuyeh polymetallic epithermal ore mineralization. Igneous phase in the Nikuyeh district are porphyritic granodiorite, monzodiorite, quartz monsonit...
