Summary:
Pg. 52. Vidrio formation. Very uniform dark- to light-gray dolomitic limestone or dolomite with a few layers of pure dolomite containing considerable chert in irregular form; in uppermost part one or two beds of reddish-brown sandstone about 4 feet thick. Thickness 2,000 feet. Correlates with Capitan limestone. Underlies Gilliam formation and overlies Word formation. Age is Permian.
This formation is most conspicuous part of Glass Mountains, Marathon region, [Brewster Co.], western TX. Vidrio is Spanish word for glass and is often used among local Mexican population as a name for the mountains.
