Distribution Comments:
Hamilton County Chert occurs as nodules near Evant, Texas. It has
been suggested that these might be associated Comanche Peak Limestone
Formation or the Walnut Limestone Formation of the Fredericksburg Group.
The Comanche Limestone Formation comfortably overlies the Walnut
Limestone Formation, which overlies the Edward Limestone Formation.
Geological references do not mention chert occurring in the Walnut or
Comanche Peak formations, but chert is abundant in the Edwards Limestone
Formation. This might be a variation of Edwards Chert.
