This thesis presents two studies employing computational approaches to tephra source attribution and tephra volume estimation. Glass major oxide data was used to train 11 classification algorithms. Each classifier probabilistically attributed tephra chemistries to one of ten volcanic sources from...

Records of atmospheric mercury deposition and post-depositional mobility in peat permafrost archives from central and northern Yukon, Canada
DownloadFall 2017
Environmental archives provide a feasible means for studying the biogeochemical cycling of heavy metals including mercury (Hg). Although many temperate peat bogs have been successfully used to reconstruct natural and anthropogenic atmospheric Hg deposition fluxes, northern circumpolar permafrost...

Natural peridotitic diamonds form in the 'diamond window' (DFW), an area of the upper mantle bounded by temperatures of 900-1400°C and pressures between 4 and 7 GPa. This study has experimentally tested and shown the viability of a hydrous, halide bearing silicate melt as a possible diamond...

A new approach to understanding the origin of Fuerteventura, Canary Islands (Spain): A U-Pb, Hf and O isotope and minor- and trace- element detrital zircon study
DownloadSpring 2019
The Canarian Archipelago contains seven islands proximal to the African continent and High Atlas Mountains. The origin and magmatic evolution of these islands has been a contentious issue for several decades. This particular archipelago is unique because three of the islands (Fuerteventura, La...
