Pg. 67-69. Lemons Bluff member of Marble Falls formation. Black subcrystalline uniformly bedded siliceous chert-bearing limestone weathering to yellowish and grayish-brown tints; locally contains quantities of minute sponge spicules. Layers are 2 to 12 inches thick and characterized by flat smooth surfaces and commonly separated by thin partings of shaly limestone. Member changes to shale beds eastward and crops out at McAnelly's Bend along Colorado River west of Bend as black fissile shale containing thin layers of dense black limestone. This shale has long been considered typical Smithwick; it ranges in thickness from a few feet to 125 feet and unconformably overlies Big Saline beds. Underlies Smithwick formation. Age is Early Pennsylvanian.
Lemons Bluff is on San Saba River, San Saba Co., central TX.
