Magmatic differentiation is the process by which a single melt produces a range of igneous rock types, and is vital for the formation of Layered Intrusions- however the timescales that magmatic differentiation occurs upon are poorly constrained. My research at UBC seeks to apply high resolution U-Th-Pb, U-Th/He and Ar-Ar dating methods to the Paleocene Skaergaard Intrusion in East Greenland- a classic testing ground for basic magmatic differentiation- to resolve timescales and develop a complete thermochronologic study from emplacement to crystallization using accessory minerals (eg., zircon, apatite and rutile). Resolving magmatic timescales to tens of thousands of years enables high resolution correlation with regional events such as the continental breakup of the North Atlantic and the Paleocene-Eocene Thermal Maximum (PETM).
