摘要

总结了埃及南部晚白垩世和古近纪早期的沉积历史和相发育。埃及中部首次报道了G.eugubina带，那里没有砾岩，通常标志着白垩纪/第三纪边界的不整合。马斯特里赫特阶上部地层属于M.prinsii带，在调查样品中未发现马斯特里赫特晚期指数有孔虫Abathom phalus mayaroensis（Bolli）。

Maastrichtian to Paleocene facies evolution and Cretaceous/Tertiary boundary in Middle and Southern Egypt

The sedimentary history and facies development of southern Egypt during the Latest Cretaceous and Early Paleogene is summarized. The G. eugubina Zone is reported for the first time from middle Egypt, where the conglomerate usually marking a disconformity at the Cretaceous/Tertiary boundary, is absent. The Uppermost Maastrichtian strata are attributed to the M. prinsii Zone, the Late Maastrichtian index foraminifer Abathom phalus mayaroensis (Bolli) was not recovered in the investigated samples.

期刊介绍： The journal is international and publishes original manuscripts in Spanish and, preferentially, British spelling English on all aspects of broad interest in palaeontology. Particularly, the SJP aims to communicate and promote palaeontological research to the global scientific community. Moreover, articles on new discoveries and approaches are especially welcome. Finally, studies of present-day material can be included if they have significant palaeontological relevance.
