Summary

The Cabin Branch and Cabin Creek (Cappy Avenue) outcrops are located along two small creeks in Prince George’s County, Maryland. The Cabin Branch outcrop contains exposures of silty sands of the Upper Cretaceous Severn Formation, and both outcrops contain Paleocene silty quartz and glauconitic sands of the Danian Brightseat Formation and highly fossiliferous glauconitic quartz sands of the Selandian Aquia Formation. Data from these two locations were generated in order to designate a Principal Reference Section for the Danian age Brightseat Formation. The Cabin Branch outcrop consists of disjunct exposures along an approximately 0.4-mile section of the creek. At the nearby Cabin Creek (Cappy Avenue) outcrop a more complete Brightseat/Aquia [...]

Purpose

Differentiation between the Upper Cretaceous and Paleocene sediments has historically been difficult to determine in the Salisbury Embayment, despite the presence of a significant hiatus separating them. Similarities in sediment composition, a paucity of exposed outcrop material, significant burrowing, and weathering have all contributed to this difficulty. As part of the U.S. Geological Survey project Atlantic Subsurface Stratigraphic Initiative (ASSI), Upper Cretaceous and Paleogene deposits from classic localities in Maryland and Virginia, as well as from proposed new cores, are being examined with the goal of providing a regional context for Paleogene sedimentation in the Salisbury Embayment, especially as it pertains to aquifer studies across state boundaries.
