Lead Pb and zinc Zn are common base metals widely used in modern industrialization Due to their incompatible geochemical properties Pb Zn tends to partition and accumulate in Earth s crust Gao et al 1998 Hofmann 1988 Galena PbS and sphalerite ZnS two essential Pb Zn ore minerals occur in several sediment hosted and
Interestingly all large scale Zn Pb deposits and most of medium to small scale Zn Pb deposits in the SYG area are hosted in the rocks underlying the Emeishan flood basalts and the deposits hosted in the the Dengying Formation account for about 46% of the proven Zn Pb reserves Liu and Lin 1999a Liu and Lin 1999b; Chen 2015 Tan et al
The Fankou is a world class carbonate hosted Zn Pb deposit characterized by the huge ore reserves more than 10 Mt Zn Pb metals and high ore grade 15 % ranking as the fifth largest carbonate hosted deposits globally Leach et al 2005 A complex series of multiple orebodies are concealed in a narrow area ∼1200 m long from north to south ∼800 m

The Pb Zn deposits in the SYG province are hosted in the Late Sinian Devonian Carboniferous and early Permian carbonate rocks A close association of these deposits with the Permian Emeishan flood basalts led Xie 1963 to classify them as distal magmatic hydrothermal deposits Evidence linking mineralization to basaltic magmatism includes the occurrence of
The orebodies are in clear contact with their wallrocks A total of 11 Cu Pb Zn orebodies were delineated which can be grouped into the No I II Ⅴ VII and VIII ore belts Figs 2 b and 3 These ore belts are parallel to fault F 1 and NW dipping Among these ore belts Nos II and VII have the largest ore resources and highest ore grades

Plots of δ 66 Zn vs δ 65 Cu 206 Pb/ 207 Pb vs δ 65 Cu and 206 Pb/ 207 Pb vs δ 66 Zn of this study The bi plots between Pb isotopes and either Cu isotope or Zn isotopes are shown in Fig 3 b and c Due to the large variability of Pb isotopes in road paint and brake pads Pb isotopes were not distinguished from these pollution sources
The coastal area of southeastern China is well endowed with W Sn Cu Pb Zn Ag and Au deposits Mao et al 2013 Hu et al 2017 forming one of the most important polymetallic metallogenic belts in China Fig 1 The central Fujian area in the central domain of the southeastern coastal metallogenic belt hosts several base metal sulfide deposits; and
The Tiemurt Pb Zn Cu deposit is situated in the southern margin of the Chinese Altay Orogen Fig 2 It was first discovered in 1987 with contained metals of Mt Pb Zn and Mt Cu Wan et al 2010a Some geological and geochemical characteristics of primary VMS mineralization are preserved at Tiemurt but the major Pb Zn Cu mineralization is adjacent to

The Smt ores differ with different spatial locations with Smt ores formed at the vent have δ 66 Zn values of ‰ to ‰ the massive Smt formed close to the vent show a value of ‰ and those formed away from the vent show a value of ‰ all values being close to 0 The sulfides have δ 66 Zn values of −‰ to ‰ The C O isotopes of Smt
The Kipushi deposit Zn Cu Pb Cd Ag Ge Ga is located in the southeastern part of the copper belt of Shaba It is remarkable for its mineralogical wealth and its economic importance This is also the case of the uranium deposit of Shinkolobwe U Ni Co Au
Soil pollution caused by potentially toxic metals PTMs is a world recognized environmental problem The excessive accumulation of PTMs Cr Cu Zn As Cd Hg and Pb in soil has seriously affected the grows of crops and the quality and safety of food and further affected human health through the food chain [19] [21] [30] Various physical remediation
On an ore field scale some Cordilleran Cu bearing mineralization is thought to be part of a porphyry Cu system An example is the Zn Pb Ag Cu Bi mineralization at Cerro de Pasco and Cu Zn Pb Au Ag mineralization in the Colquijirca district of Peru which are thought to be located in the upper parts of Cu bearing porphyries
Due to the rapid development of industrial and agricultural activities heavy metals have been widely detected in the soil Liu et al 2020b Owing to the persistence high toxicity and non biodegradability heavy metal contaminated soil has been considered as an increasingly severe environmental problem Liu et al 2018b Cd Pb Hg As Cr Ni Cu and
