Keri L Belcher , M.S., expected 2018 (Co-supervisor)
I'm a first year Master's student studying the Campanian age, shallow marine, clastic sedimentary deposits of the Cretaceous Western Interior Seaway in Wyoming. My research focuses on the Blair Formation, which is considered to be an isolated shallow marine sandstone. Isolated shallow marine sandbodies are abundant along the Cretaceous Western Interior Seaway and commonly act as hydrocarbon traps. An integral...
