Description: "Although about 70 percent of known terrestrial meteorite impacts involve sedimentary rocks, the response of such rock to hyper- velocity impact is not well understand. Evans (Missouri State U., Springfield) introduces a dozen papers from a session on impact geology at the 2004 Geological Society of America Annual Meeting. Arranged by rocks' stratigraphic order (oldest to youngest) in proximal and distal settings, papers study topics including: characterization of impact sediments; a model for impact cratering processes; development of breccias (rock composed of sharp fragments embedded in a fine- grained matrix) in the Chesapeake Bay impact structure; and the method of impact stratigraphy applied to aging of the K-T boundary associated with mass extinction. The well-illustrated volume is not indexed."--Publisher's website.
