Stratigraphic Analysis with Refraction Tomography

Publication Abstract:

Near-surface seismic refraction tomography imaged the basal contact of the Upper Cambrian silica-rich Mt. Simon Formation with that of the underlying Precambrian granite in central Wisconsin.  The discrimination between the Mt. Simon and underlying non-conformable contact with Precambrian rocks was based upon a p-wave velocity of 1,700 m/s.  Refraction tomography imaged deep, broad tidal channels within the Mt. Simon consistent with the inference that Mt. Simon was deposited in a high-energy near-shore probably fluvial environment.  The Mt. Simon is an arenite that has high commercial value.
