"[Map in Book] Geologic Map of Texas [in] The Geology of Texas Volume I Stratigraphy",

This detailed and colorful map locates twelve different geological groups in the state through the use of color and pattern. An inset continues the main map revealing the geologic detail of the panhandle, and an extensive legend describes each geological group. The map is based on the U.S.G.S.' preliminary map of 1932 along with data from numerous other sources (including somewhat larger maps that were issued by the university in 1916 and 1919). Prepared by E.H. Sellards, W.S. Adkins, and F.B. Plummer within the University of Texas Bureau of Economic Geology. This handsome map of the state folds into a rear pocket of the 1,007-page volume entitled The Geology of Texas. The text is primarily comprised of the following reports: "The Pre-Paleozoic and Paleozoic Systems in Texas" by Sellards; "The Mesozoic Systems in Texas" by Adkins; and "Cenozoic Systems in Texas" by Plummer. Additional illustrations include a frontispiece photographic plate illustrating the Guadalupe Mountains and 5 fossil plates. Octavo, hardbound in red cloth with gilt titles on front cover and spine.
