Integrated biostratigraphy of two Upper Maastrichtian – Palaeocene successions in north-central Sinai, Egypt
Integration of the calcareous nannofossil and planktonic foraminiferal biostratigraphies has been performed for theUpper Maastrichtian – Palaeocene successions at Gebel Umm Khushayb and west El-Hassana sections (north-centralSinai, Egypt). The studied successions include the uppermost part of the Su...
