An Expanded Chesapeake Bay Impact Structure, Eastern Virginia: New Corehole and Geophysical Data

Data from several deep coreholes, seismic reflection surveys, and surface mapping indicate that the buried Chesapeake Bay impact structure is wider (160 km, due to 35-km-wide outer fracture zone) and deeper (2 miles) than previously reported. Additional information is contained in the original extended abstract.

Integrated Geologic, Hydrologic, and Geophysical Investigations of the Chesapeake Bay Impact Structure, Virginia, USA: A Multi-Agency Program

The Chesapeake Bay impact structure is the focus of an ongoing federal-state-local research program. Recent core drilling and geophysical surveys address the formative processes and hydrogeologic properties of this major "wet-target" impact. Additional information is contained in the original extended abstract.
