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.
