This trip is open to all geoscience students and represents an opportunity to see classic Lower Cretaceous carbonate outcrops in central Texas. We will visit Glen Rose Formation and Edwards Group outcrops northwest of San Antonio to study rudist reef, interreef and platform interior depositional settings. Included will be a close examination of the physical scale and depositional facies associated with a Lower Cretaceous patch reef complex that is spectacularly exposed along the banks of Red Bluff Creek.
The complex, comprised primarily of large caprinid rudist bivalves, is situated some 30 miles seaward of the Late Aptian shore. Within the overlying Edwards Group, diagenesis and porosity modification resulting from early dissolution, dolomitization, large-scale solution collapse and fracturing will be examined at the Vanderpool roadcut that exposes over 400 feet of Edwards carbonates. We plan to have a BBQ dinner for all participants prior to our return to San Antonio.
NOTE: This field trip can be bought as a package with the AAPG-SC/SEPM Student Short Course for only $50.
