|Woodbine Formation, East Texas Basin
Field-specific petrographic descriptions of the Woodbine (Wagner, 1978) show fairly mature mineralogic compositions, sublitharenite to litharenite. Quartz in the dominant mineral and feldspar, clay, shell fragments, and chlorite is present. Accessory minerals reported include pyrite, organic materials, and micas. Albite is present but volumes were not quantified.
