David Summer – PhD candidate, University of Toronto Solomons hydrothermal systems David is developing a lithotectonic map of the seafloor around the Solomon Islands and in the Coral Sea, using bathymetric and geophysical data. He will also characterize the geology and (isotope) geochemistry of the Stanton seafloor massive sulfide deposit, Vanuatu Arc, SW Pacific, to…
Jennifer Spalding – PhD candidate, uOttawa Alpine orogeny thermochronology Jennifer uses apatite fission track data to derive low temperature thermal histories of shallow crustal processes. Jennifer uses apatite chemistry and fission track ages as thermochronometers to produce thermal history models and understand the timing of metallic ore and hydrocarbon deposition. Jennifer finished her BSc Hon.…
Jessie Kehew – MSc candidate, uOttawa Lau basin sequence stratigraphy Jessie is investigating the order of sub-basin opening within the Lau Basin with the use of parasound acoustic data and seismic data. The bounding structures and echo-facies of the sub-basins will be compared to inter-assemblage sedimentary basins of the Abitibi Greenstone Belt, with special emphasis…
Jonathan Umbsaar – PhD candidate, University of Toronto Lithotectonic sub-classification of Seafloor Massive Sulphide Deposits Jonathan’s research focusses on actively-forming Seafloor Massive Sulphide (SMS) deposits across tectonic settings, and as a function of their critical metal endowments, in order to identify a more robust means of sub-classification of SMS deposits that accounts for the dominant…
Michael Ryan – MSc candidate, uOttawa Lau Basin-North Fiji magmatic productivity Michael is mapping and analyzing volcanic features of four assemblages in the Lau and North Fiji basins in order to determine the variability and controls on magmatic productivity. He is using bathymetry and backscatter data to better understand these modern microplate domains, comparing them…
Octavio Acuña Avendaño – PhD candidate, University of Toronto Mariana geodynamics and hydrothermal systems Octavio is studying the tectonism, magmatism, and hydrothermal venting in the Mariana back-arc. This framework is used to identify the lithospheric controls on magmatic-hydrothermal systems in the Mariana back-arc and how they affect the distribution, temporal evolution, and geochemical composition at…
Sabrina Chan – MSc candidate, Carleton University Northern Nevada caldera structures Sabrina is studying Eocene igneous activity of the Stone Cabin Caldera in eastern Great Basin ignimbrite province. She is using major/trace elements and isotopic (Sr-Hf-Nd-Pb) data to determine the magma source and potential crustal contaminants, ultimately aiming to define the boundary between Phanerozoic and…
