 Nomenclature. — This, the lower of the two main Taylor chalks in northeastern Texas and known previously under various names in the literature, was given the name Gober by Stephenson in 1927 (1534, p. 8). The type locality is the village Gober, south-central Fannin County, Texas.

 Areal outcrop. — So far as is now known, the outcrop of the Gober is restricted to Fannin, Lamar and possibly western Red River counties, Texas. In the Clarksville section, there is a chalk in the position of the Gober, just above the Brownstown marl (392, fig. 3, page 81); this chalk, exposed at White Rock about 7 miles northeast of Clarksville, is stated by Stephenson (1534, p. 11) to have a lower stratigraphic position than the Pecan Gap ( = upper Annona), being separated from it by a band of chalky clay or marl, but containing a similar micro-fauna. East of the Clarksville area the Gober is not recorded. Thomas and Rice (1601a, p. 964) state:

 The Gober chalk, occurring on the outcrop and in wells in northeast Texas, is a lower Taylor tongue and not a part of the true Austin chalk. In several respects it is more closely related to the lower Pecan Gap chalk than to the Austin and is intermediate in position.

 The Gober chalk extends eastward from the upper part of the thickened body of Austin Taylor chalk outcropping in southwestern Fannin County. Where it connects with the main body of chalk overlying the Bonham clay it is as much as 400 feet thick, but to the east it thins, and in eastern Lamar County appears to pinch out entirely. According to Stephenson this eastward thinning of the Gober may be partly caused by basal strata of Gober changing into the marl facies of the underlying Brownstown and thus becoming indistinguishable from that member. In the area between Honey Grove, Fannin County and High, Lamar County, the lowest part of the Gober is in part composed of soft, more or less chalky clay or marl. The lowest layers of chalk, which are exposed in a cut about 1¼ miles west of High, are regarded as forming the base of the Gober, Eastward this chalk probably interfingers into and changes over into clay. The uppermost bed of Gober, from central Fannin County to eastern Lamar County, is a soft, tough limestone, 1 to 10 feet thick, which is suitable for building stone. Paleontological evidence indicates that the Gober is of younger age than the Austin type (1534, p. 8).

 Above the Gober and below the Wolfe City sand, there is a considerable thickness of Taylor clay, continuous with the main body of type Taylor in south-central Texas and passing eastwards through northwestern Hunt County, southeastern Fannin County, southern Lamar and Red River counties and into southwestern Arkansas. In Red River County in Stephenson's opinion the greatly expanded Annona chalk goes far enough down in the column to take in the equivalents "not only of the Pecan Gap chalk, but of the underlying Wolfe City sand member of the Taylor marl, and of most, if not all, of the still lower Taylor beds as they are developed in Lamar and Red River counties."
