Sulfur isotopes of host strata for Howards Pass (Yukon ...

A new sulfur isotope stratigraphic profile has been developed for OrdovicianSilurian mudstones that host the Howards Pass ZnPb deposits (Canada) in an attempt to reconcile the traditional model of a stagnant euxinic basin setting with new contradictory findings. Our analyses of pyrite confirm the upsection 34S enrichment reported previously, but additional observations show parallel ......

Carbonatehosted leadzinc ore deposits

Carbonatehosted leadzinc 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 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 ......

Testing the structural and geomechanical processes in the ...

all PbZn deposits occur in extensional setting, as several other varieties reportedly occur in compressional settings, during contraction (, Garven 1985; Oliver 1986; Duane and de Wit, 1988; Bradley and Leach, 2003). Moreover, when giant accumulations of ZnPb are found in complexly deformed terrains (which record both extensional and compressional tectonic regimes), identifying the ....

Orogenic mineral system | Geoscience Australia

The most important example of Cobartype CuAuZnPbAg deposits is the 405385 Ma Cobar district in New South Wales (Glen et al., 1992; Perkins et al., 1994), with the minedout Woodcutters deposit in the Pine Creek mineral province another example. Associated critical commodities. Although Au, Cu, Zn, Pb and Ag, in that order, are the main products of the orogenic mineral system ......

Lithogeochemical exploration for shalehosted PbZn ...

The geological and lithogeochemical setting of shalehosted PbZn deposits worldwide was studied. The geology of south Cork (500km2) was mapped on a 1" scale and a lithogeochemical survey involving the collection and analysis of 475 rock samples for 26 major and trace elements by ICPAES was laid out. A data processing method based on petrochemical parameters rather than statistics was ......

New insights into the metallogeny of MVT ZnPb deposits: A ...

ZnPb deposits hosted by carbonate or siliciclastic rocks con tain the world's greatest Zn and Pb resources and predominate the world production of these metals (Leach et al. 2005). They are known as sedimenthosted types of ore deposit and generally have no direct genetic association with igneous activity (Leach et al. 2010). Carbonatehosted ZnPb deposits, one of the two major subtypes ......
