摘要：

Land-sea correlation off NW Africa is investigated from both modern and late Pleistocene/Holocene pollen records. Pollen spectra from modern soil surface samples from Senegal and Mauritania and from modern bottom sediment samples from the offshore eastern Atlantic (21-12°N) record accurately the latitudinal vegetation zonation of West Tropical Africa, by showing the maximum percentages of the phytogeographical groups and the same characteristic taxa as the adjacent vegetation zones. A strong correlation between marine (core M-16017-2 near Cap Blanc) and continental (sebkha of Chemchane, Mauritania) pollen signals is also observed for the evolution of the late Glacial/Holocene vegetation zonation at 21°N. The differing sensitivities of each sedimentary environment for recording local and/or subcontinental vegetation changes are discussed. © 1990.
