The sulfides are also characterized by homogeneous and relatively low radiogenic Pb isotope compositions 206 Pb/ 204 Pb = 207 Pb/ 204 Pb = and 208 Pb/ 204 Pb = similar to the Pb isotopic compositions of the associated volcanic rocks The Pb isotopic data indicate that mantle derived Pb is more
Hydrothermal alteration and geochemical proximity indicators to ore at the Metsämonttu Zn Pb Cu Au Ag deposit Uusimaa belt southern Finland chemostratigraphic results suggest that the lithological and/or structural setting of the Metsämonttu succession is more complex than previously considered The stratigraphic footwall is
Skarn systems constitute a major source of the world s Pb Zn W Sn Fe Cu Mo and Au Meinert et al 2003 Chang et al 2019 and are genetically related to the emplacement of dioritic to granitic plutons in active subduction zones to post subduction tectonics Meinert et al 2005 Sillitoe 2010 A clear documentation of their distinct alteration styles and
Barite and apatite can also be common in some cases Other elements associated with Zn and Pb ore zones include Cu As Cd Sb Tl Hg Se Bi Ge and Ni are more similar to the siliciclastic mafic Zn Pb sub Regions that yield high WOE prospectivity scores and low standard deviation represent the highest priority for mineral
In this contribution S and Pb isotopic measurements were carried out for the Baoshan Cu Pb Zn deposit Combined with the systematic analyses of previously published S and Pb isotopic data of the major granite related Cu Pb Zn deposits and geochemical data of the host rock granitoids in the Qin Hang ore belt this study aims to provide geochemical
Request PDF On Nov 1 2023 Zhan Ke Li and others published A giant porphyry skarn epithermal Mo W Cu Zn Pb Ag metallogenic system in the Nannihu ore field southern North China Craton
The Qingchengzi Pb Zn polymetallic ore district in northern China records two stages of Pb Zn mineralization in the Paleoproterozoic and Mesozoic respectively The Paleoproterozoic sedimentary metamorphic stage stage I of mineralization was primarily recorded by stratiform ores and the Mesozoic magmatic hydrothermal stage stage II of
The Weibao Cu Pb Zn deposit initially discovered through geochemical reconnaissance survey by the Geophysical and Geochemical Party Xinjiang Bureau of Geology and Mineral Resource Exploration and Development GGPXBGMRXD in 2003 is located at the boundary of Xinjiang and Qinghai China 37°07′58″ N 91°07′08″ E Fig 1b and now has
The Baiyangping Cu Ag polymetallic ore district is located in the northern part of the Lanping Simao foreland fold belt between the Jinshajiang Ailaoshan and Lancangjiang faults and the deposit can be divided into eastern and western ore zones Based upon microscope observation of ore minerals and analysis of zinc copper and strontium isotope composition we conclude
Volcanogenic massive sulfide VMS deposits are one of the most important sources of metals mainly Cu Zn Pb ± Au in the world Mercier Langevin et al 2011 Hannington 2014 de Ronde et al 2019 Metallogenesis of this kind of deposit is often complex and multistage making it difficult for ore geologists to obtain detailed ore forming information
The Sichuan Yunnan Guizhou SYG Pb Zn metallogenic province is located on the southwestern margin of the Yangtze Block with a complex geological environment and superior metallogenic conditions Han et al 2014 The SYG district is an important component of the low temperature metallogenic domain of South China Hu et al 2017 The SYG district
Song et al 2023 studied the metal sources of the Zhugongtang Zn Pb deposit in northwestern Guizhou province South China The results suggest that sphalerite is the main Cd bearing mineral and Cd was most likely incorporated into sphalerite via Fe 2 Cd 2 ↔ Zn 2 substitution The different Cd isotopes and Zn/Cd ratios support a mixing model for the
Red mud RM was used to remediate heavy metal contaminated soils Experiments with two different dosages of RM added to soils were carried out in this study It was found that soil pH increased and unit with the dosage of 3 and 5% wt% respectively At the dosage of 5% the highest stabilization efficiencies for Cd Pb Cu and Zn reached
The results demonstrate that the ore consists of 35 categories of minerals assaying Cu % Pb % and Zn % in the forms of chalcopyrite galena and sphalerite respectively and silver
To date a total Pb Zn reserve of 13 Mt Yu et al 2008 has been estimated of which the Changba Lijiagou Pb Zn deposit is the largest with a proven Pb Zn reserve of 7 Mt % Pb and % Zn on average; Gu et al 2007 As the second largest Pb Zn deposit in China after the giant Jinding Pb Zn deposit in Yunnan Province the
Although Jurassic granites are closely associated with W Sn polymetallic mineralization in this belt some of these granites are mostly enriched in Cu Pb and Zn More studies have been conducted
The Tiemurt Pb Zn Cu deposit metal reserve Mt Pb Zn and Mt Cu is hosted in the Kangbutiebao Formation volcanic sedimentary rocks in the Chinese Altay Orogen NW China
Orogenic gold deposits are the main source of gold reserves in the world and their geochemical characteristics and tectonic settings are known to geologists Groves et al 1998 The possibility and potential of orogenic type Ag Pb Zn Cu Mo and other metals are proposed considering their geochemical similarities Chen et al 2004b Chen 2006 Pirajno
