Available in PDF, EPUB and Kindle. Book excerpt: In southwestern Wyoming, the Bajocian to Callovian Twin Creek Limestone records the incipient deposition on a foreland basin in the Sundance Seaway. The sequence stratigraphy of the Twin Creek Limestone is described in the Wyoming Range of southwestern Wyoming, and the geometry of the foreland basin is described mathematically based on estimates flexural rigidity of the underlying crust and the subsidence caused by a thrust load in central Idaho. Four depositional sequences are described. These sequences are correlated to the Bighorn Basin based on existing biostratigraphic correlations and descriptions of the sequence stratigraphic architecture of Middle Jurassic strata in the Bighorn Basin. Modeling of the flexural subsidence of the foreland basin indicates that to account for the geometry of the foreland basin some form of long-wavelength subsidence must be superimposed on the flexural subsidence associated with the thrust load in central Idaho
