Summary:

The Cuevas Limestone, here named, consists of fragments of calcareous algae in a matrix ranging from pure crystalline calcite to impure detrital limestone. Overlies tuffaceous conglomerate or siltstone of the Coamo Formation with angular unconformity. Conformably underlies post-Cuevas rocks. Age is Tertiary(?).
