High-resolution speleothem paleoclimatology of northern Venezuela: a progress report. Boletín Sociedad Venezolana de Espeleología 36

ABSTRACT Stalagmites from four caves of northern Venezuela were collected for paleoclimatology studies. Preliminary age determinations and carbon and oxygen isotope data from a stalagmite, show a major stable isotope shift from approximately 11,500 to 10,000 years ago similar to the Sajama ice core...
