"Lost Creek Bed" of Albany division (of Drake, 1893) is here revised--assigned as Lost Creek shale [member] of newly named Admiral formation of Wichita group (revised) in the Colorado River Valley, north-central TX on Bend arch. Author's note: There is a tendency among geologists to refer to the Permian in the Albany and Wichita areas as the "Albany-Wichita group" and to speak of the marine limestone facies of the Brazos Valley as "Albany Beds" and the red strata of the Red River as "Wichita Red Beds." Lost Creek is not present in Brazos River Valley. In Brazos River Valley the Admiral formation is divided into following members (ascending): unnamed limestone and shale; and Elm Creek limestone. In the Colorado River Valley members are (ascending): Lost Creek shale; Hordes Creek limestone; unnamed limestone and shale; and Elm Creek limestone. In a section measured along the Santa Fe RR, 3 1/2 mi southwest of Coleman, Coleman Co, TX, Lost Creek consists of shale, 46 ft thick. Measured section. Stratigraphic chart. Of Permian age.
