Pg. 24, 31; Univ. Texas Bull., no. 2132, p. 127-134. Gonzales Creek member of Graham formation. In southeastern Young County, Brazos River region, central northern Texas, 230+/- feet of shale and sandstone occur above Jacksboro limestone. This portion of Graham formation of Brazos River Valley is named Gonzales Creek member, for a creek in Eastland County [?]. Where Jacksboro limestone is absent the Gonzales Creek member rests on underlying Finis shale. It underlies Bunger limestone member of Graham formation, and is composed of poorly bedded, lenticular dark-brown sandstones, sandy shales, red clays, gypsiferous black clays, 2 limestone lentils, and a coal bed. The sandstones are lenticular and the shales are variable. One limestone lentil occurs 30 feet below Bunger limestone and the other 80 feet below the Bunger. [Age is Pennsyvlanian.]
Named from Gonzales Creek [now Gunsolus Creek, located in Stephens and Eastland Cos.], Brazos River region, central northern TX (additional locality information from USGS GNIS database, accessed April 23, 2012).
