The Geology Of The Egyptian Nubian Shield

This richly illustrated book provides an overview of the Neoproterozoic Pan-African Belt of Egypt (PABE), which represents the northwestern continuation of the Arabian-Nubian Shield (ANS) and the East African Orogen (EAO). The first chapter offers an introduction to the Turin Papyrus Map and the historical background of the PABE, while the second addresses how the PABE is related to the ANS and EAO. Rock succession of the PABE is dealt with in Chapter 3, while Chapter 4 focuses on Sinai Metamorphic Core Complexes and implications on the break-up of Rodinia. Subsequent chapters discuss a broad range of topics, e.g. ophiolite-dominated suprastructural rocks; volcanosedimentary succession, Neoproterozoic volcanism and volcanic rocks in Egypt; enigmatic issues concerning granite, Dokhan and Hammamat sediments; the lithospheric mantle beneath the Northeast African continent and the mantle section of Neoproterozoic ophiolites from the PABE; sutures, megashears and petrogenetic evolution of the Neoproterozoic rocks of Egypt; and metallic and non-metallic mineral deposits in the PABE, which are covered in extensive detail. The book’s closing chapters discuss the application of remote sensing techniques and anisotropy of magnetic susceptibility (AMS) to decipher the tectonic evolution of the PABE, as well as the use of geophysical data to map structural features and hydrothermal alteration zones in the PABE.

This richly illustrated book reviews the geology, tectonics and mineralization of the Arabian-Nubian Shield (ANS) in 27 chapters. It starts with an examination of the ANS lithospheric scale features, explores Mesoproterozoic units and deals with the ANS oceanic stage. Arc volcanism and plutonism, post-collision basins and volcanics are discussed, as well as the younger granitoid magmatism and the deformation history of the ANS. The book provides information on ANS glacial stages and late magmatism. Chapters are devoted to review the transition between ANS and the reworked continent to its south. Finally, it discusses how ANS structures influenced the overall East African Rift System.

Evolution and Mineralization of the Arabian–Nubian Shield, Volume 1 presents the exploration for mineral resources in the Precambrian basement terrain underlying large areas of the Middle East. This book discusses the geological investigations of the tectonic evolution, structure, and metallogenesis of the Arabian–Nubian Shield. Organized into four parts encompassing 15 chapters, this volume begins with an overview of the study of the geology of the western Saudi Arabia. This text then examines the Pan-African basement, which has all the geological and geophysical characteristics of continental crust. Other chapters consider the tectonic evolution of parts of the central and southern Eastern Desert by using the available satellite images and detailed field work in specific areas. This book discusses as well mineralization and geological outline of the Red Sea Hills and the Nile Valley. The final chapter deals with the separation of the African and Arabian plates. This book is a valuable resource for geologists.

Evolution and Mineralization of the Arabian-Nubian Shield, Volume 2 documents the proceedings of a Symposium on the Arabian-Nubian Shield. This book is divided into five main topics — structure and evolution; metallogenesis; plutonic rocks; metamorphic rocks; and ophiolites. In these topics, this text specifically discusses the Precambrian tectonics of North-East Africa; cratonic ore provinces separated by continental drift; peralkaline granite in the western part of the Arabian Shield; and Semail ophiolite and associated massive sulfide deposits. The Upper Proterozoic volcanic activity in the northern Arabian Shield; ore controls at the Mahd adh Dhahab gold mine; shallow intrusive granites from Egypt and their relation to mineralization; and chromites from the Al'Ays and Semail complex are also deliberated. This text is a good reference for students and individuals interested in the exposure of Precambrian crystalline rocks on the borders of the Red Sea.

This book presents a detailed review of the mineral deposits and occurrences in the Arabian-Nubian Shield (ANS), including their distribution, mineralization styles, economic importance, and geological controls on the mineralization. The purpose of the book is to compile the results of past and recent investigations on mineral deposits and occurrences in the ANS that covering the countries of (Saudi Arabia, Yemen, Egypt, Sudan, Eritrea, and Ethiopia). In this regard, it discusses in detail the various genetic mineralization styles in the ANS including: (1) magmatic mineral deposits associated with mafic-ultramafic rocks (e.g. chromite, Ni-Cu-Co-PGE magmatic sulfides, Fe-Ti-V oxides), (2) intrusion-related (magmatic-hydrothermal) deposits associated with felsic to intermediate rocks (porphyry, epithermal Au-Ag/sulfide vein type family, skarn, granite-related pegmatite-REE deposits), (3) hydrothermal orogenic gold and volcanogenic massive sulfide (VMS) deposits, as well as (4) surficial mineral deposits (chemical-sedimentary, residual, mechanical and supergene enrichment deposits).
