Title: Upper Cretaceous-Lower Eocene Strata, Hainesville, Keechi, and Oakwood Salt Domes, East Texas: ABSTRACT

Author(s): Edgar H. Guevara, Alice B. Giles

Article Type: Meeting abstract


Salt domes in east Texas are possible sites for nuclear waste repositories. Tectonic stability is a critical factor in evaluating suitability as a repository. Subsurface studies were undertaken to determine stratigraphy and

structure of strata around the domes, and to ascertain the growth history of the domes as a means to evaluate tectonic stability. Upper Cretaceous to lower Eocene strata bound the upper part of the domes. Three main types of domes have been interpreted from well-log data: (1) at Hainesville dome, Upper Cretaceous strata exhibit notable thickening in a rim syncline, and stratigraphic markers dip toward the dome except near the contact with domal material; (2) at Keechi dome, strata are uplifted and dip away from the dome; strata thin toward the dome; (3) at Oakwood dome, strata are approximately horizontal until near the dome edge, where they are upturned; minor thickening of strata occurs toward the dome. Differences in stratigraphy and structure of Cretaceous-Eocene strata in the vic nity of these domes are attributed to differences in growth history.
