Correlation and Causes of Fifth Order Cycles Within the Upper Cretaceous Eagle Formation, Bighorn Basin of Wyoming
… Upper Cretaceous (Santonian-Campanian) section (Eagle Formation) within the Bighorn Basin of Wyoming. Of particular concern was the 10<sup>3</sup> to 10<sup>4</sup> year band, which in marine settings has been attributed to orbital forcing (Milankovitch cyclicity). A series of 19 sections were …

Evolution and Architecture of an Incised Valley in the Upper Cretaceous Eagle Formation in South-Central Montana
The Santonian-Campanian Eagle Formation in south-central Montana is composed of a series of exceptionally well preserved regressive-transgressive cycles deposited on the western margin of the Cretaceous Interior Seaway. This study focuses on the genesis of a regionally correlative basal incision …

Condensed and Expanded Sections in the Lower Mesaverde Clastic Wedge, Campanian of Wyoming: Evidence for Tectonic Rectification of Sea Level
… This thesis focuses on two members of the Eagle Formation in the Bighorn basin of Wyoming, USA, the Virgelle and the Gebo, whose contrasting architectures appear to reflect oscillatory sea level fall (the Virgelle) versus pulsed sea level rise (the Gebo). I hypothesize that Gebo deposition …
