Atypical MVT, Zn-Cu-rich mineralization in the lower portion

Mississippi Valley-type (MVT) deposits of the Viburnum Trend are typically lead-dominant (Pb:Zn > 5) and occur mainly in the reef-grainstone facies of the upper Bonneterre Dolomite (Cambrian). Recent drilling has encountered economic mineralization within the lower Bonneterre Dolomite and underlying Lamotte Sandstone, more than 30 m below the

Skarn deposits of China - [email protected]

The Zn-Pb mineralization may be part of either an oxidized system (e.g., Cu, Mo, Fe) or a reduced system (e.g., Sn). In China, distal Zn-Pb is more commonly related to reduced magmas. Gold and W may also be related to both oxidized and reduced magmas, although in China they are more typically related to oxidized magma.

Dating of the Giant Huize Zn‐Pb Ore Field of Yunnan

The Huize Zn‐Pb orefield is typical in this respect because the primary ore consists only of galena, sphalerite, pyrite, and calcite. Many attempts have been made to date Zn‐Pb deposits (Chesley et al., 1994; Jiang et al., 2000) using the Sm‐Nd method. The Sm‐Nd method has emerged as a useful tool because Sm and Nd are both rare earth

Ore Genesis of the Chuduoqu Pb-Zn-Cu Deposit in the Tuotuohe

The Chuduoqu Pb-Zn-Cu deposit is located in the Tuotuohe area in the northern part of the Sanjiang Metallogenic Belt, central Tibet. The Pb-Zn-Cu ore bodies in this deposit are hosted mainly by Middle Jurassic Xiali Formation limestone and sandstone, and are structurally controlled by a series of NWW trending faults. In this paper, we present the results of fluid inclusions and isotope (C, H

Lead isotopes of the carbonate-hosted Kabwe, Tsumeb, and

Lead isotope ratios of galena from the carbonate-hosted massive sulphide deposits of Kabwe (Pb-Zn) and Tsumeb (Pb-Zn-Cu) in Zambia and Namibia, respectively, have been measured and found to be homogeneous and characteristic of upper crustal source rocks. Kabwe galena has average isotope ratios of 206/204Pb = 17.997 ± 0.007, 207/204Pb = 15.713 ± 0.010 and 208/204Pb = 38.410 ± 0.033.

Jan 01,  · Pb, Zn, Ni, Cu and Cr are essentially bound to residual fraction of the sediment (up to 50%). However, these metals are also bound to oxyhydroxides. In the case of Pb and Zn, the exchangeable fraction and carbonates are an important carrier fractions. This suggests that a some percentages of these metals are toxic because they are bioavailable.
