Marquez Dome is the filled and eroded remnant of an about 15-km diameter, 58 Ma impact into unconsolidated sediments in Southeast Texas. The 3-km diameter central peak outcrops as Cretaceous marls and shales at the surface and is flanked by pre- and postimpact tertiary sands and clays. Petroleum exploration data for Marquez include over 160 km of reflection seismic data criss-crossing the site and numerous logged wells. These data have been used to roughly define the extent of the central peak from a zone of no continuous reflectors and the rim from low-angle, modest offset normal faults. A minimum group interval of 33 m and near offset of 100 m cause the industrial seismic data to be of low quality in the upper 250 ms, and consequently these lines do not image the flanks of the central peak and the shallow rim faults. We conducted a shallow seismic investigation to see if engineering seismic equipment could be used to image the flanks of the central peak and fill in the missing 250 ms in the industrial data.
