 — Some sediment-hosted base metal deposits, specifically, the clastic-dominated Zn-Pb deposits, carbonatehosted Mississippi Valley-type (MVT) deposits, sedimentary rock-hosted stratiform copper deposits, and carbonate-hosted polymetallic ("Kipushi-type") deposits, are or have been important sources of critical elements …

 — Lead (Pb) is among the most toxic heavy metals in biological systems and causes toxicity from seed germination to yield formation. High Pb concentrations lead to oxidative damage and impair water relation and nutrition uptake in plants. Rye (Secale cereale L.) is an abiotic stress-tolerant crop, distributed in Eastern and Central Europe. …

 — 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 …

 — Purpose Heterogeneity of soil mineral particles may lead to the misinterpretation of bulk sorption data on their role in metal sorption, which may be resolved through the direct observation of metal distribution among the soil particles after the sorption. Materials and methods Analytical transmission electron microscopy was used …

 — The Zn dissolved from Zn-sulfide during the weathering processes at pH 2–3 may have eventually formed Zn mineral complexes with Fe (oxyhydr)oxides and ... Our previous research demonstrated that the neutral pH condition in the hardpan formed at the surface sulfidic Cu-Pb-Zn tailings could restrict Zn co-dissolution with ferrihydrite and re ...

 — In the main stage Cu-Pb-Zn mineralization, Cu was precipitated prior to Pb and Zn. The Cu mineralization in the mylonites is dominated by stockworks while breccia mineralization is common in Pb-Zn ores and the fragments are cemented by sphalerite, galena, and pyrrhotite (Zhong et al., 2012). Ore fabrics and mineral assemblages of Cu …
