Summary: In the Eyreville drillcore, which was drilled within the central part of the Chesapeake Bay impact structure, about 154 m of suevite were recovered [1]. We present a petrographical and geochemical study of the suevite; furthermore, the proportions of unshocked and shocked quartz grains are evaluated based on systematic analyses of quartz grain properties.
