Summary:

Pl. 3, p. xxxvi, 17, 22. Timber Belt or Sabine River beds. Silceous sand and greensand marls, with smaller quantities of white, brown, and black clays and with frequent beds of lignite. Often impregnated with vegetal matter to such an extent that numerous traces of petroleum, asphalt, and natural gas have been found. Thickness 800 to 1,000 feet. Underlie Fayette beds and overlie Basal clays [Wills Point clays]. Age is Eocene.
Timber belt beds named from great timber region of eastern TX. Sabine River beds named from Sabine River, eastern TX. Notable exposures in Houston, Marion, Cass, and Henderson Cos., eastern TX.
[GNC remark (ca. 1938, US geologic names lexicon (USGS Bull. 896, p. 2150): †Timber Belt beds included Wilcox group, part of Claiborne group, and Jackson of present classification. Sabine River beds included Wilcox group and part of Claiborne group.]
