The boundaries of the Ark-La-Tex area are arbitrarily defined and the exploration history of the area briefly reviewed. A Basal Upper Cretaceous structure map and two stratigraphic cross sections illustrate the regional tectonic movements contributing to the formation of the East Texas basin, the North Louisiana basin and the intervening Sabine Uplift. Exploration objectives and problems and the relation of magnetic and gravity anomalies and axes with regional geologic trends and structure are discussed. It is pointed out that the piercement dome type structure offers an almost untested field for further exploration. Illustrations include a vertical intensity magnetic map with contour interval of 100 gammas, a Bouguer gravity map with contour interval of 5 milligals and type seismograph records.
