Spring 2021
Diamonds, due to their inert and robust nature, encapsulate and preserve minerals, recording the mantle substrate in which they form. Forming in the subcontinental lithospheric mantle over a protracted period, diamonds provide snapshots of craton formation and mantle evolution over much of...

Stable isotope development in ground ice along an alpine tundra slope in the Ogilvie Mountains, Yukon Territory
DownloadSpring 2022
Stable isotopic ratios of oxygen and hydrogen (δ18O and δD) from ground ice have been used to reconstruct paleoclimate temperatures spanning the Late Pleistocene and Holocene in subarctic and arctic regions. This is possible due to the strong relations between the isotopic composition of...

The Evolution of Magmatic-Hydrothermal Fluids as Recorded by Stable Cl Isotopes and Cl/Br Elemental Ratios in Geothermal Systems, Porphyry Copper and Iron-Oxide-Copper-Gold Deposits
DownloadFall 2015
This research was conducted with the purpose of identifying the processes that affect the halogen distribution and the Cl isotope composition of hydrothermal fluids under different pressure and temperature conditions in the crust. In order to attain this goal, three different geological settings...
