... of this Bulletin (page 470), that the term Yeager clay be hereafter used to designate the lithologic unit overlying the Fayette sandstone in south Texas and consisting of dominantly non-volcanic clays of various colors, the president of the San Antonio Geological Society, Herschel H. Cooper, appointed a committee...

..., and several hundred feet in maximum thickness, the name Yeager is proposed, from the Yeager Ranch on the Cotulla-San Diego road in northeastern Webb County. The clays are exposed, at intervals, from a distance of approximately ¼-½ mile east, to 3½ miles southeast, of the ranch house, where...

The remaining question then is that of the name to be applied to the clay...

Samples of humus and B-horizon soil were collected at 25–50-m intervals over traverses with the total lengths of 562 m over the Whiskey kimberlite and 740 m over the Yankee kimberlite pipe.

Das and Zoback (2013a) suggest that LPLD events result from slow shear slip on preexisting faults that are unfavorably oriented in the present-day stress field or have high clay content.
