Geochemistry, Mineralogy, and Absolute Ages of Caribbean Sediment Core: ABSTRACT
1969
Chemical and mineralogic variations in a deep-sea core dated by the Io/Pa method show that during interglacial periods the content of detrital minerals (quartz and muscovite) reach a maximum, whereas clay minerals are more abundant during glacial periods. The concentration of Mn is higher during glacial periods. The data suggest that in the Caribbean area chemical weathering was at a maximum during glacial periods; during interglacial periods conditions were more arid.
