|Woodbine Formation, East Texas Basin
Structure on top of the Woodbine was digitized from Core Labs (1972). Contours were gridded by using the Grid algorithms in ARC/INFO, and depth below land surface was calculated by using the U.S. Geological Survey digital elevation model (c1woodbineg). A more detailed, large, plate-size structure map was presented by Calavan (1985).
