摘要:Abstract(#br)The present work presents new field observations on the geological characteristics of the Neoproterozoic ophiolites of the Central Eastern Desert (CED) of Egypt. Based on mode of occurrences, the investigated ophiolites appear to show characteristics of both MORB-...

摘要:... These ophiolites may provide significant insights into the convergence history of the South China Block during the Rodinia supercontinent cycle. SHRIMP zircon U–Pb dating indicates that the SAO formed at 831 ± 5 Ma whereas the NJO formed at ca. 1000 Ma. Modal mineral ass...

摘要:Abstract(#br)Tectonic mélange fragments (metabasalt and metadiabase) in the ophiolitic serpentinites of the Egyptian Eastern Desert show peculiar mineral assemblages and they provide useful insights into metamorphism and metasomatism. New field and mineralogical data indicat...

摘要:Abstract(#br)U-Pb and Lu-Hf isotopic analyses of zircon from albitites, southern Brasiliano Orogen, indicate Neoproterozoic ages for two ophiolites. The difficulty of dating ophiolites is overcome by finding zircon in albitites contained in serpentinite. Two key areas were selec...

摘要:Abstract(#br)The Neoproterozoic peridotite-chromitite complexes in the Central Eastern Desert of Egypt, being a part of the Arabian-Nubian Shield, are outcropped along the E–W trend from Wadi Sayfayn, Wadi Bardah, and Jabal Al-Faliq to Wadi Al-Barramiyah, from east to west. T...

摘要:Abstract(#br)Ophiolites are key components of the Neoproterozoic Arabian–Nubian Shield (ANS). Understanding when they formed and were emplaced is crucial for understanding the evolution of the ANS because their ages tell when seafloor spreading and terrane accretion occurre...

摘要:Abstract(#br)Geochemical and SmNd isotopic data are presented for two Neoproterozoic ophiolite suites (∼970 Ma), which were tectonically emplaced into the Banxi Group and equivalent sequences of the Yangtze Block in the southern Anhui and northeastern Jiangxi Provinces, sou...

摘要:Abstract(#br)The Transcaucasian Massif (TCM) in the Republic of Georgia includes Neoproterozoic–Early Cambrian ophiolites and magmatic arc assemblages that are reminiscent of the coeval island arc terranes in the Arabian–Nubian Shield (ANS) and provides essential evidenc...
