Title: Structural Interpretation of Recent Gravity Observations in Southeastern Oklahoma

Author(s): Thomas A. Hendricks (2)


Fourteen new gravity determinations have been made by the United States Coast and Geodetic Survey on and near the north border of the Coastal Plain in southeastern Oklahoma. The stations are located near township corners and form a grid surrounding the junction of the Ouachita and Arbuckle mountain systems beneath Cretaceous strata of the Coastal Plain. Gravity anomalies computed by the Coast and Geodetic Survey show a broad nose of high positive anomalies that coincides with the granite core of the Tishomingo anticline of the Arbuckle Mountains and with its southeastward prolongation beneath the Coastal Plain. The nose extends southeastward in such a way as to form a large southeastward reentrant at least 12 miles deep in the northwest front of the Ouachita Mountain stru tural province between Atoka, Oklahoma, and Denison, Texas.
