“…Whittle et al (1995) reported that during the Middle and Late Eocene times, a major regression took place associated with a large uplift in Arabia and Iran exposing all of that area for extensive erosion. Such conditions are also recorded by (Abdulsamad et al, 2009) in the Benghazi area (NE Libya) where, the Lower Oligocene unconformably overlies Middle Eocene sediments. The broader regional effects of this tectonic activity across the Eocene/Oligocene unconformity are observed in many countries of the Arabian plate, including Saudi Arabia, Kuwait, Bahrain, south Iraq, Qatar, where the Miocene deposits lies directly above the Middle Eocene Dammam Formation (Alsharhan and Nairn, 1995).…”

An effort has been made to evaluate drainage morphometry and its influence on landform processes, geology and erosion characteristics in Jordan Valley and surrounding area. Geological maps 1:50,000 scale and the professional Google Earth images were used for analysis of various morphometric, lithological and landform characteristics of Jordan Valley basin. Morphometric analysis was carried out at sub basin level using Geographic Information Systems (GIS) and Globel Mapper (GM) to analyze the influence of drainage morphometry on landforms, drainage pattern and land erosion. Different landforms were recognized in the basin based on visual exposition of 3D Digital Elevation Model (DEM) that obtained from the thousands of points of the elevations by using GIS and GM, escarpments, plateau spurs, narrow wadies âvalliesâ and main wadies floor, foot slopes. The sub basins that take number 2, 5 and 6 are associated with high density dentritic drainage pattern because of impermeable formation and high slope then high surface runoff and high erosion. The sub basins number 1, 3, 4 are associated to a low density dentritic drainage pattern due to the topography of the area that is flat shape and the formation is impermeable. A1, A2 and A3 are a trellis drainage pattern with high density because of the moderate slope and high fracturing formation

“…A perusal of the literature suggests that orthophragminids from southern Tethyan platforms are poorly understood, while groups as nummulitids, rotaliids and alveolinids seem to be fairly well established at species level (Abdulsamad, Bu-Argoub, & Tmalla, 2009;Al-Sayigh, 1998;Amard & Blondeau, 1979;Belkhodja & Bignot, 2004;Bishay, 1961;Boukhary, Hewaidy, Luterbacher, Bassiouni, & Al-Hitmi, 2011;Di Carlo et al, 2012;El-Khayal, 1974a, 1947bFermont, 1982;Haynes et al, 2010;Hottinger, 2014;Kenawy, 1976;Pignatti et al, 1998;Racey, 1995;Robinet et al, 2013;Sander, 1962;Schwager, 1883;Smouth, 1954;White, 1994;Wielandt, 1996;Zittel, 1883). The detailed work from Israel (Fermont, 1982) provides valuable information on the generic and specific identity of late Ypresian-Lutetian orthophragminids inhabiting the continental margin of the Arabian Plate.…”

“…These recurrent episodes are evidenced by the recurrent syndepositional mass movements of sediments and unconformities over time (El Hawat and Pawellek 2005). The gradual disappearance of deep-water marine fauna during the early Eocene (Apollonia Formation) and the gradual appearance of large nummulitids and coarsening upward of allochems during the middle Eocene (Darnah Formation) indicate a shallowing-up trend that lasted until the end of Miocene (Abdulsamad et al 2009). One of the very interesting features in this region is the dominance of unconformity surfaces.…”

Libya is located on the southern shore of the Mediterranean Sea in the northern part of Africa. Geomorphological landforms known as geomorphosites are those that have been seen or exploited by humans as having scientific, cultural/historical, aesthetic, or social/economic significance. Various geomorphosites transverse Libya and can be found in other parts of the world. United Nations Educational Scientific and Cultural Organization (UNESCO) geoparks need to conduct a comprehensive inventory of such geomorphosites to protect, promote, and geoconserve these sites for future generations. Geotourism promotion in Libya offers a great opportunity for the local community to grow and prosper. Additional African and developing countries with attractive geosites and landforms that can be promoted as geotourism destinations should be included in this initiative. The present study evaluates and assesses the geomorphosites in Cyrene and Apollonia. These sites are considered to possess regional importance, whose particular archeological and world heritage sites are indexed in UNESCO World Heritage, which makes the region a unique study subject. The area is highly recommended to be a geopark. Libya’s substantial geological assets, notably geoheritage, are enhanced in this study. These resources can promote local, sustainable development through scientific research, educational initiatives, geotourism expansion, and diversification of Libya’s isolated desert areas.
