One of the world's largest concentrations of sediment-hosted stratiform zinc-lead-barite deposits is (Figure 1). The largest and most developed of these is located in the Gataga area of northern British Columbia the CirqueiSouth Cirque deposit, with estimated geological reserves of 38.5 million tonnes averaging 8.0% Zn, 2.2% Pb and 47.2 gitonne Ag at Cirque and gitonne Ag at South Cirque (M...

Abstract The Paleoproterozoic Mârmorilik Formation in the Karrat basin of West Greenland hosts Black Angel Zn–Pb deposit. Chlorine-rich scapolite, zones with vuggy porosity and quartz nodules ore-bearing marble are herein interpreted to represent metamorphosed, vanished, replaced evaporites, respectively. Mineralization is closely associated anhydrite δ 34 S values (5.2–12.6‰) broadly comparabl...

Zn-Ni-Cd alloy was electrodeposited from an alkaline electrolytic bath under potentiostatic conditions. Bath analyses using a pH concentration diagram reveal that addition of a complexing agent is essential to maintain the bath stability. Introduction of a low concentration of CdSO4 reduces the anomalous nature of the Zn-Ni deposit. Deposits obtained from the electrolytic bath which contains 60...

Abstract Various genetic models have been proposed for the supergiant Proterozoic Broken Hill Pb–Zn–Ag deposit largely based on geological and geochronological evidence. Here we present Zn, Cd S isotope compositions as well Zn/Cd ratios of sphalerite from minor Hill-type deposits (Australia) to help constrain these but focus syngenetic magmatic–hydrothermal processes, since epigenetic can be re...
