Thesis Defence: Timing of ductile shear along the Wopmay fault zone

May 29 at 9:00 am - 1:00 pm

Kelsey Krossa, supervised by Dr. Brendan Dyck, will defend their thesis titled “Timing of ductile shear along the Wopmay fault zone” in partial fulfillment of the requirements for the degree of Master of Science in Earth and Environmental Sciences.

An abstract for Kelsey Krossa’s thesis is included below.

Defences are open to all members of the campus community as well as the general public. Registration is not required for in person defences.


ABSTRACT

The Wopmay fault zone (Wfz) is an approximately 300 km long, north-south striking, dextral transform fault zone located in the Northwest Territories, Canada between the western margin of the Slave craton and the eastern boundary of the Great Bear magmatic zone and Hottah terrane. As the loci of suturing between the Slave craton and Hottah terrane, the timing and kinematics of ductile deformation along the Wfz holds valuable information pertaining to the tectonic evolution of western Slave cratonic margin and the broader history of amalgamation of western Laurentia. In this thesis, I present new in-situ U-Pb apatite geochronology, apatite trace element chemistry and electron backscattered diffraction data collected from seven metaplutonic samples across the Wfz. Collectively, these data are interpreted as recording a near continuous history of dextral shear recrystallization in the Wfz that spanned 1890 ± 16 Ma to 1832 ± 14 Ma.
