Characterization of Indicator Minerals and Till Geochemical Dispersal Patterns Associated with the Pine Point Pb-Zn Mississippi Valley-type Deposits, Northwest Territories, Canada
DownloadFall 2013
Surficial geological mapping of the Pine Point region records three, possibly four, directions of ice flow. Dispersal of metal-rich till was primarily to the north and west indicating that at least the oldest ice flow trajectory was in contact with mineralized bedrock. This metal-rich till...

Geochemical Characterization and Fluid History of the Tiger Zone; a Tertiary Distal Carbonate-Replacement Intrusion-Related Gold Deposit, Central Yukon
DownloadSpring 2013
A paragenetic and geochemical study has resulted in the classification of the Tiger zone as a Tertiary-aged intrusion-related gold deposit. Gold-bearing mineralization occurs in two geochemically and temporally distinct assemblages. The first assemblage contains carbonate-replacement,...

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...
