摘要
During the Paleocene and Early Eocene, three main events affected the stratigraphic distribution of the planktic foraminifera in the area of the Farafra Oasis. The first one at the K/Pg boundary is characterized by a stratigraphic gap corresponding to most of the lower Paleocene. The second event starts in the upper part of the Praemurica uncinata Zone (P2) and extends into the Globanomalina pseudomenardii Zone (P4a). It is marked again by a stratigraphic gap corresponding to most of the Middle Paleocene or to numerous short diastems. The third event is the widespread "velascoensis-event". All three events are also reflected by the intensive reworking of older faunas.
