Summary:

Unit is named the Wadleigh Limestone. Consists of a medium- to dark-gray thick- to medium-bedded, massive, commonly fetid fragmented-fossil limestone, with argillaceous interbeds. Thickness is estimated at 1000 ft but could be as much as 2000 ft. Upper and lower contacts are nearly everywhere covered. Conformably overlies the Karheen Formation or Coronados Volcanics. Conformably underlies or is intercalated with the Port Refugio Formation or underlies the Peratrovich Formation. Age is Middle and Late Devonian age based on fossils [corals].
