Zinc-lead deposits hosted by Lower Cambrian carbonate rocks near Huayuan in the Hunan-Guizhou orogenic belt southern China have been studied by means of Pb and Sr isotopes.
KEYWORDS Economic geology Kootenay arc lead-zinc carbonate hosted lead isotopes. INTRODUCTION Fieldwork for this study consisted of a preliminary inves- tigation and sampling of carbonate-hosted lead-zinc deposits within the Kootenay arc. Lead isotope data from galena were also determined at The University of British Columbia.
Economic Geologists International Field Conference on Carbonate-Hosted Lead-Zinc Deposits held in St. Louis Missouri June 3-6 1995.
Mississippi Valley-type MVT deposits are epigenetic stratabound carbonate-hosted sulphide bodies composed predominantly of sphalerite galena iron oxides pyrite marcasite and carbonates calcite dolomite. MVT deposits are important Zn and Pb reserves and resources in the world. Silver barite gypsum and fluorite may also be economically recovered from these deposits.
Ore deposits are crustal concentrations of useful elements that can be exploited at a profit. Like all crustal rocks they consist of minerals. Carbonate-hosted stratabound lead-zinc deposits Mississippi Valley-type Lennard Shelf.
Carbonate-Hosted Base Metal Deposits Fred Kamona University of Namibia Namibia 1. Introduction Carbonate-hosted base metal sulphide deposits are discussed with reference to ore deposit mineralogy and geology isotope geochemistry ore fluids and ore genesis of type exampl es. Three main carbonate-hosted deposit types are recognized 1.

Carbonate Hosted Lead Zinc Ore Deposits - Mineralogy and Alteration. Mineralogy and Alteration. Ore minerals in carbonate replacement deposits are typically lead sulfide galena and zinc sulfide sphalerite. Weathered equivalents form anglesite cerussite hydrozincite and secondary galena and sphalerite within the supergene zone..
Carbonate-hosted lead-zinc ore deposits are important and highly valuable concentrations of lead and zinc sulfide ores hosted within carbonate limestone marl dolomite formations and which share a common genetic origin.. These ore bodies range from 0.5 million tonnes of contained ore to 20 million tonnes or more and have a grade of between 4 combined lead and zinc to over 14 combined.
