| contents | Reconstruction of climatic zonation and features of surface water circulation in the Indian Ocean for seven selected time intervals is presented based on DSDP/ODP data on distribution of planktonic foraminifera species in Neogene sediments of the Indian Ocean with regard to new palinspastic reference schemes. In Neogene two climatic signs are recognized: at the end of Early Miocene and in Early Pliocene. The equatorial divergence and the monsoon-related Hindustan upwelling presumably existed since Early Miocene, and the Arabian-Somalian upwelling is traced at least since Middle Miocene. In Late Miocene, latitudinal zonation was established over the entire area of the ocean, while in Early-Middle Miocene its northwestern part significantly differed from the northeastern one. |
