title: Oxygen isotopic analysis of the size fraction between 62 and 250 micrometers in Caribbean cores p6304-8 and p6304-9.
abstract: Oxygen isotopic analysis of the carbonate sediment fraction between 62 and 250 micrometry yields curves following the general trend of those obtained from Globigerinoides sacculifera. Warm stages 11, 13, and 15 are characterized by heavy postdepositional solution. which makes the sediment fraction between 62 and 250 micrometers rich in shell fragments of the more resistant, deeper-living species. As a result, oxygen isotopic analysis of these samples yields comparatively low temperatures, in contrast to those obtained from Globigerinoides sacculifera.
