Abstract Many existing research focuses on the differences or performance comparisons between single‐atom small‐sized nanocluster catalysts, but there is a lack of comprehensive coupling relationship structure and activity mechanism synergy. This study investigates combined catalytic potential cobalt single atoms (SAs) nanoclusters (NCs) for enhanced peroxymonosulfate (PMS) activation to degrade norfloxacin (NFX). A novel Co SAs‐NCs /CN/TiO 2 catalyst synthesized, featuring SAs NCs uniformly...
The newly discovered Nayongzhi Zn-Pb deposit (>20 Mt ores at 1.11–15.65 wt% Zn and 0.59–0.97 Pb) in NW Guizhou province, South China, is hosted by late Ediacaran early Cambrian carbonate rocks. ore body structurally controlled a kilometer-scale reverse fault-anticline system occurs as stratiform, lentiform, or steeply dipping vein structures. Its geological feature comparable to that of the Mississippi Valley-type (MVT) deposits. δ34S values (+11.8 +33.0‰) sulfide minerals determined...
Abstract Regolith-hosted rare earth element (REE) deposits have been the focus of recent studies. Most studies concern formed over granites and felsic volcanic rocks, but little is known about those developed silica-undersaturated alkaline igneous rocks. The recently discovered Puxiong REE deposit in Southwest China through weathering nepheline syenite that has concentrations ranging from 177 to 9,336 ppm. Hydrothermal processes partially enriched parent REEs. About 60% REEs bedrock are...
Hydrothermal alteration minerals are an effective prospecting indicator. Advanced spaceborne thermal emission and reflection radiometer (ASTER) satellite data some of the most commonly adopted multispectral for mapping hydrothermal minerals. Compared to data, hyperspectral have stronger ground object recognition ability. Chinese Gaofen-5 (GF-5) is first independently developed by China that has advantages both wide-width high-spectral-resolution technology. However, ability GF5 requires...
Abstract: Trace elements and rare earth (REE) of the sulfide minerals were determined by inductively‐coupled plasma mass spectrometry. The results indicate that V, Cu, Sn, Ga, Cd, In, Se are concentrated in sphalerite, Sb, As, Ge, Tl galena, almost all trace pyrite low. Ga Cd contents light‐yellow sphalerites higher than brown black sphalerites. Tl, It shows REE concentrations galena. In sphalerites, concentration decreases from to ratios Ga/In more 10, Co/Ni less 1 studied pyrites,...
Abstract Unraveling the evolution of Mississippi Valley-type (MVT) hydrothermal system is crucial for understanding ore genesis and exploration. In this paper, we take Wusihe Pb-Zn deposit in western Yangtze Block (South China) as a case study, using detailed geology, quartz situ trace elements, sulfides S-Pb isotopes, to propose new integrated model MVT system. Four stages were identified district: (I) lamellar pyrite-sphalerite; (II) disseminated, stock-work, brecciated sphalerite-galena;...
Accurately determining the age of hydrothermal ore deposits is difficult, because lack suitable mineral chronometers and techniques. Here we present first LA-MC-ICPMS U-Pb carbonates from Sb deposits. Three stages giant South China metallogenic belt were identified: (1) pre-ore dolomite (Dol-I), (2) syn-ore calcite (Cal-II), (3) post-ore (Cal-III). The U Pb isotopic data show that Cal-II yielded a lower intercept 115.3 ± 1.5 Ma (MSWD = 2.0), suggesting mineralization corresponds to an...
As geosciences enter the era of big data, machine learning (ML) that is successful in now contributing to solving problems geosciences, yet there have been few applications economic geology. This paper highlights effectiveness ML-based methods coupled with mineral geochemistry revealing origin Qingchengzi Pb–Zn ore field China, which are either metamorphosed sedimentary exhalative (SEDEX) or magmatic–hydrothermal fluid related deposits. Laser ablation–inductively plasma–mass spectrometry...
The Benue Trough stretching about 800–1000 km with a width ranging between 100 and 150 km, is megarift structure whose origin was related to the opening of south Atlantic during early Cretaceous. This mega rift contains economically significant Pb-Zn-Ba-F deposits that form well-defined metallogenic belt 600 long in Nigeria. In Southern (SBT), are localized four districts namely Abakaliki, Ishiagu, Wanikande Gabu-Oshina hosted by carbonaceous shale; Central (CBT) deposit silicified limestone...
Abstract The Tianbaoshan Pb–Zn deposit, part of the Sichuan–Yunnan–Guizhou (SYG) metallogenic province, is located in western Yangtze Block and contains 2.6 million tonnes 10–15 wt.% Pb + Zn metals. Ore bodies occur as vein or tubular types are hosted Sinian (late Proterozoic) carbonate rocks structurally controlled by SN-trending Anninghe tectonic belt NW-trending concealed fractures. deposits simple mineralogy, with sphalerite, galena, pyrite, chalcopyrite, arsenopyrite, freibergite,...
