My thesis project is located in the Nechako basin of south-central British Columbia. The Jurassic to Tertiary sedimentary rocks that form the Nechako basin have demonstrated high petroleum prospectivity. However, these rocks have been subjected to widespread Eocene magmatic, thermal and structural events that have extensively modified and complicated the basin architecture. In addition, the considerable thicknesses of volcanic strata now mask the hydrocarbon host rocks, resulting in a challenging interpretation of the seismic data. The same volcanic rocks that are a barrier to petroleum exploration host several epithermal deposits, however most of them are not easily accessible because of the extensive glacial drift cover. The objective of my project is to provide a regional structural framework and evolution of the Nechako basin during the Eocene to allow better identification of pre‐Eocene hydrocarbon bearing features, and to help constrain the metallogenic impact and potential of the Eocene volcanic rocks. Overall, the outcome of this study will be applicable to both hydrocarbon and mineral exploration industries in British Columbia, by allowing improved reconstruction of the basin architecture and better assessments of resource potential.
