Abstract Details

2007, Master of Science, Miami University, Geology and Environmental Earth Science.
The Jurassic Curtis, Summerville and Stump formations of Utah and Colorado consist of marine and marginal-marine strata deposited along the southern margin of the Western Interior Seaway. Although previous investigations have documented the distribution, lithologic characteristics, and environments of these units, they have been difficult to correlate regionally due to internal lithofacies variations and the lack of age-diagnostic fossils. In this study I present new data consisting of 34 biostratigraphic samples and 25 measured stratigraphic sections demonstrating the stratigraphic equivalency of the Curtis and Summerville formations with the Stump Formation and demonstrate that deposition occurred between early and late Oxfordian time (~161-155 Ma). Detailed sedimentological field data allows formulation of a sequence-stratigraphic model that indicates these formations were deposited during a single transgressive-regressive sequence. The new sequence stratigraphic model helps clarify the stratigraphic architecture of the Middle-Upper Jurassic rocks of the region and may serve as a guide for interpretations of other tidally-influenced depositional systems.
