Depositional history of the upper Calvert Bluff and lower Carrizo formations, Bastrop, Texas uri icon

abstract

  • This fi eld trip examines exposures of transgressive and highstand marine deposits of the Sabinetown transgression that forms the upper part of the Calvert Bluff Formation of the Wilcox Group in the outcrop belt. The horizon of maximum fl ood in the Sabinetown transgression at Bastrop contains molluscs and diverse vertebrate fossils characteristic of open marine environments. The highstand deposits coarsen upward and are capped with a well-developed paleosol. These deposits are dated as early Eocene. 2013 Geological Society of America.
