Caraba Formation (Panama)

The Caraba Formation (Tcr) ^[1] is a geologic formation in Panama. The formation was first defined in 1950 by Jones as a facies member of the Caimito Formation. ^[2] The formation consists of poorly lithified, pebbly, tuffaceous, calcareous sandstones and conglomerates and preserves fossils dating back to the Early Oligocene period. ^[3]
