NOTA SOBRE LA EDAD DE LAS CALIZAS CORALINAS DEL PLEISTOCENO MARINO EN LAS ISLAS DE SAN ANDRÉS Y PROVIDENCIA (MAR CARIBE OCCIDENTAL, COLOMBIA)

Abstract

Radio carbon dates of coral samples from Pleistocene reef terraces of the Western Caribbean islands of San Andres and Providencia, indicate ages of coral deposits ranging from 26,000 to 33,000 years. Contamination of coral skeletons with atmospheric i4C isotopes subsequent to exposure of terraces to atmosphere cannot be completely ruled out. So the values obtained may represent only minimum ages, and the terraces in fact could be considerably older. The dates, however, exclude a recent to subrecent age, that former authors.
