Lithophile and Chalcophile Elements in Sphalerite from the Anarraaq Sediment-Hosted Zn-Pb-Ag Deposit, Red Dog District, Alaska
DownloadFall 2017
The age of many sedimentary hosted base metal deposits has been a topic of debate for several decades, due to a lack of minerals ideal for geochronological age in these systems. One technique is focused on dating the ore minerals (sphalerite) directly with the Rb-Sr method. The main issue with...

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...

The paragenesis and geochemistry of the Bellekeno Ag-Pb-Zn vein, Keno Hill district, Yukon, Canada
DownloadFall 2013
The Keno Hill district Ag-Pb-Zn deposit occurs within the Tombstone-Tungsten Belt, Yukon. Vein mineralization, dominated by siderite, sphalerite, and galena, is spatially associated with, but paragenetically later than, intrusion-related gold mineralization. A direct genetic link between the Keno...
