The Oligocene Palynology and Palaeoclimates of Northern Egypt as Recorded in the Dabaa Formation

The Phanerozoic Geology and Natural Resources of Egypt

Abstract

In this chapter, we present the story of the Oligocene palynostratigraphy and floral composition in Egypt as told by the preserved palynomorphs in the Dabaa Formation. It is a step in establishing a regional biostratigraphic and vegetational framework for the Oligocene, thus making future integration of regional and global schemes possible, especially when more independent biostratigraphic information becomes available. Synthesis of published materials from surface and subsurface sections points to significant floral changes during the Oligocene time leading to the development of a number of different vegetation belts in this part of North Africa. These include coastal mangrove forests, back-mangrove wetland ecosystems such as freshwater marshes, lakes, and swamps, as well as inland forests and open woodland-savannah habitats. The prevailing climate is interpreted to have been warm and humid with local or seasonal dry conditions.
