The objective of my research is map the subsurface architecture of Jurassic sandstone beds in northeastern British Columbia. There will be a focus on depositional environments, sediment distribution, stratigraphic correlations and reservoir potential. The thesis will employ both outcrop and subsurface studies, including core and well logs. I will employ genetic and sequence stratigraphy to create a predictive model of sandstone bed geometries. Provenance studies will assist with a tectono-stratigraphic model for the period when the passive margin developed into a tectonically active foreland basin. Also, the information gathered will help to build a including a predictive, regional high-resolution paleogeographic framework for the time period.
