Jinchanghe is a Zn-Pb-Fe-Cu skarn deposit in the northern Baoshan block, southwestern China. It is a typical distal skarn deposit with orebodies in the Cambrian Hetaoping Formation limestone and calcareous siltstone. The skarn minerals display a vertical zonation with garnet skarn in the lower part and pyroxene skarn in the upper part. Economic metals are also …

The Pulang super-large porphyry Cu polymetallic deposit, located in the Sanjiang area of Yunnan Province, is one of the largest Cu deposits in China. This deposit hosts Cu resources of ~5 × 106 t and other ore-forming elements, such as Mo, Au, Ag, Pb, Zn, Pt and Pd. Recently, obvious hydrothermal vein-type Pb–Zn mineralization, with a Pb + Zn resource of …

The northern east of Algeria represents the most important metallogenic zone for Pb-Zn-Fe-Ba (Cu, F, Sr) ore-deposits. The mineral association consists of galena, sphalerite, barite, and celestite with gray copper, pyrite, chalcopyrite, and marcasite associated with a carbonate (dolomite and calcite) matrix. Quartz, siderite, fluorite, and oxidation products like …

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 Zn have …

The influence of different pH conditions and simulated inter-root environmental solutions on the release behavior of heavy metals (Cu, Pb, and Zn) from contaminated soils was investigated. The results indicate that heavy metal leaching from the soil is more likely to occur under acidic conditions and there is a risk of sustained presence of heavy metals in the inter …

The average concentrations of Cu, Cd, Pb and Zn in rice grains were 2.23, 10.98, 29.84 and 1.62 times their corresponding maximum allowable levels, indicating potential health risks to humans. Cd has greater bioavailability because of its high mobility from soil to roots, and its subsequent transfer to grains. ...

Determining the association of Pb–Zn(-Ag) mineralization with granite is crucial for understanding metallogeny and identifying exploration targets. The genesis of Pb–Zn-Ag-Sb deposits and their genetic association with Sb(-Au) deposits and granite-associated Sn-W deposits in the Tethys Himalaya of southern Tibet, China, remains controversial.
