摘要
In Egypt, biostratigraphic studies of calcareous nannofossils from the Miocene-Pliocene successions are scarce, irregular, and limited to certain areas. The present study is based on a review of calcareous nannofossils from 28 wells in the Gulf of Suez, North Nile Delta, and 7 exposed surface sections from west central Sinai (Egypt). Fifteen calcareous nannofossil zones from NN2 through NN16 are evaluated and discussed in this study. The NN2-NN3 of early Miocene; NN4 of early/middle Miocene boundary; NN5-NN6 of middle Miocene; NN7 of middle/late Miocene boundary; NN8-NN11 of late Miocene; NN12 of Miocene/Pliocene; NN13-NN15 of early Pliocene and NN16 of middle Pliocene are enumerated. The calcareous nannofossil events are also correlated regionally and globally and the Miocene and Pliocene Stage boundaries are also briefly discussed.
