Precambrian Ophiolites and Related Rocks
Author: T.M. KuskyPublisher: Elsevier
ISBN: 0080473938
Category : Science
Languages : en
Pages : 762
Book Description
Recent developments have shown that many full and partial ophiolites are preserved in Precambrian cratons. This book provides a comprehensive description and discussion of the field aspects, geochemistry, geochronology and structure of the best of these ophiolites. It also presents syntheses of the characteristics of ophiolites of different ages, and an analysis of what the characteristics of these ophiolites mean for the thermal and chemical evolution of the earth. This title emphasizes new studies of Precambrian Geology that have documented ophiolites, ophiolitic fragments, and ophiolitic melanges in many Precambrian terranes. Each chapter focuses on individual Precambrian ophiolites or regions with numerous Precambrian ophiolites, and covers field aspects, petrology, geochemistry, geochronology, and other descriptive aspects of these ophiolites, it also delves into more theoretical and speculative aspects about the interpretation of the significance of these ancient ophiolites.

The Geology of the Arabian-Nubian Shield
Author: Zakaria HamimiPublisher: Springer Nature
ISBN: 3030729958
Category : Science
Languages : en
Pages : 786
Book Description
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.
Mineral Deposits and Occurrences in the Arabian–Nubian Shield
Author: Ahmed Hassan AhmedPublisher: Springer Nature
ISBN: 3030964434
Category : Science
Languages : en
Pages : 532
Book Description
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).
