Palynostratigraphic studies on the Cretaceous subsurface sediment of Ghorab-1 well from the northern part of the Western Desert have been investigated. Palynoflora are found to be derived principally from Pteridophyte spores (vascular land plants, 10 species), Gymnosperm pollen grains (13 species), Angiosperm pollen grains (14 species) and rare contribution of aquatic palynomorphs (9 taxa). The Palynoflora showed that the palaeoenvironments were favorable for different plant groups. The recovered microflora, therefore, indicated that the age nearly to Late-Albian (Kharita Formation) -Early Cenomanian (Bahariya Formation).Two distinct assemblage zones have been distinguished (I: Elaterosporites klaszii, Afropollis operculatus and II: Elaterocolpites castelainii, Cretacaeiporites polygonalis). The palynological data e.g. Elaterosporites klaszii, Afropollis operculatus, Cicatricosisporites minutistriatus, Perotriletes pannuceus and Elaterocolpites castelainii, Cretacaeiporites spp. proved also that the north Western Desert of Egypt belongs to the North Gondwana phytogeoprovince during the Cretaceous time.
