This book presents the following geological contributions in Ediacaran and Paleozoic rocks. 1) It introduces four new rock units for the first time, the Ediacaran El Urf Formation (volcanoclastic sediments in the central Eastern Desert), the Ediacaran Abu Haswa Formation (stromatolitic dolostone in southwestern Sinai), the Early Permian Wadi Dome Formation (mixed clastics and carbonates in the west of Suez Gulf) and the Early Permian Misawag Formation (in the subsurface, northwestern Desert), 2) making correlation of the Ediacaran rock units with the corresponding rock units in Libya, Jordan, Iraq and Saudi Arabia, 3) linking the exposed Paleozoic rock units with their equivalent rock units in subsurface in northwestern desert, 4) correlating the Paleozoic rock units with the equivalent rock units in adjacent countries, e. g. Libya, Jordan, Iraq and Saudi Arabia, 5) manifesting the possible depositional environments of the Ediacaran and Paleozoic rockunits. Additionally, it offers an important unique geological information about the Ediacaran and Paleozoic rock units in Egypt. It unifies the nomenclature of Paleozoic rock units that take numerous names for the same geological time. It obsoletes the formation names that do not follow the rules of the North American stratigraphic code (1983) for rock units' nomenclature. It provides the target audience illustrations, e.g. field photographs for the exposed rock units that save efforts and time for audience (undergraduate, post-graduate, researchers and professional) to reach to the original localities of each rock units. It provides the audience with schematic diagrams that exhibit the link between the exposed and subsurface rock units all over the Egyptian territory. It describes the following topics of each rock unit: definition, stratigraphic contact, lithological characteristics, faunal and floral associations that are used for the identification of the possible age, correlation with corresponding rock units in adjacent countries, e.g. Libya, Jordan, Iraq and Saudi Arabia and the possible depositional environments for each rock units.

The book is a fundamental source of an updated version of the information in the field to the undergraduate, graduate, researchers, professional, practitioners and policy planning elsewhere.

Autorentext

Mohamed A. Khalifa received his B.S. in geology from Geology Department, Cairo University in 1972, obtained a master's degree in geology from the Faculty of Science, Cairo University in 1977, and received his Ph. D. in sedimentology and stratigraphy from Faculty of Science, Cairo University in 1981. From 1973 to 1978, he worked at the Egyptian Geological Survey. During this period, he drew geological maps using aerial photographs and made a regional correlation of the Mesozoic and Cenozoic rock stratigraphic units in the Western and Eastern Deserts. From 1995 to 1999, he taught at geography department, Imam Mohamed ben Saud University at Al Qassim branch. From 2009 to 2015, he taught at Geology Department, Omar Al Mokhtar University (Libya) at Topruck branch. So far, he has published 87 research papers in the fields of sedimentology, stratigraphy, diagenesis, cyclicity and sequence stratigraphy of the Paleozoic, Mesozoic and Cenozoic rocks from Egypt, Saudi Arabia, Yemen and Jordon. He introduced five stratigraphic rock units in the Egyptian geology (Campanian Ain Giffara, Turonian Naqb Es Sillim, Turonian Khashm El Galala, Lower Eocene Nashfa and Pliocene El Reis formations). Of note, he introduced a new rock unit in the Paleozoic and Mesozoic Eras in Al Qassim Province, Saudi Arabia (Lower Ordovician Anz, Permian Al Watah, Permo-Triassic Al Arid, Upper Triassic Al Adgham and Upper Triassic the Rukhman formations). He is now an emeritus professor at Geology Department, Faculty of Science, Menoufia University, Shiben El Kom, Egypt.
