Chesapeake Bay impact structure : development of "brim" sedimentation in a multilayered marine target /
The Chesapeake Bay impact structure is a well-documented example of a small group of multi-layer, marine-target impacts formed in continental shelves or beneath epeiric seas. New sedimentological and stratigraphical data and results, mainly from Chesapeake Bay brim cores (Watkins School, Langley and...
