Geochronology and Trace Element Characteristics of Pyrite from Selected Carbonate Hosted Pb-Zn Ore Deposits
DownloadFall 2012
Carbonate-hosted ore deposits, such as Mississippi Valley-type (MVT), and Irish-type deposits, are a major class of Pb-Zn ores. Due to the mineralogy of these deposits, numerical constraints on the timing of mineralization are few. This thesis investigates pyrite Re-Os geochronology for dating...

The genesis of the Gayna River carbonate-hosted Zn-Pb deposit
Fall 2009
Geochemical analyses on samples from the Mississippi Valley Type Gayna River deposit, Northwest Territories, Canada, have resulted in the definition of three ore stages and a deposit genesis model. Pb/Pb and Re/Os isotopic analyses indicate that the mineralization at Gayna River was emplaced...
