Recent and last glacial deep-sea facies: Response to global climatic oscillations

The geographic zonation of the Recent World Ocean, as expressed by distribution of the surface water masses is reflected by latitudinal lithofacial belts and by planktonic foraminiferal assemblages. The lithofacies are controlled mainly by biological productivity and the microfossil assemblages are sensitive to sea-surface temperatures (SST). Migration of the latitudinal lithofacial belts and their boundaries during the Last Glaciation was inferred from displacement of the SST zones.
