Abstract
A palynological analysis has been carried out on the Lower Cretaceous Kharita, Dahab, Alamein and Alam El Bueib formationsencountered in the subsurface sections of the Mamura-1 (MAX-1), Mersa Matruh-1 (MMX- 1) and Burg El Arab-1(BAX-1) wells, north Western Desert of Egypt. 144 core samples have been analyzed palynologically and produced 147 species belonging to 102 genera, which allow and recognizing three informal sporomorph zones and two informal dinoflagellate zones are restricted to northern Western Desert ranging from Neocomian to Albian ages. They are correlated with the well-documented biozonations established for the same interval from other localities in the north Western Desert of Egypt and northern Gondwana regions. According to the relative abundances and paleoecologic characters of the palynomorphs, the Kharita Formation maybe deposited in an open-marine, warmer and humid climate. The Dahab and Alamein formations maybe deposited in a shallow to inner shelf environment and under humid, tropical to sub-tropical climatic conditions. The Alam El Bueib Formation maybe deposited in deltaic; warmer environment under humid climatic conditions.
