...Claude Dupuy; Catherine Mével; Jean-Louis Bodinier; Liliane Savoyant Abstract New analyses of rare earth elements (REEs) and abundances of K, Rb, Sr, Ba, Th, U, Ta, and Hf in peridotites from Zabargad Island, Red Sea, indicate that light REE-enriched amphibole peridotites in the northern...

...Enrico Bonatti; Paul Hamlyn; Giulio Ottonello Abstract Information on the nature of the upper mantle in a young rift zone with lithosphere transitional from continental to oceanic was obtained from the island of Zabargad, probably an uplifted fragment of Red Sea lithosphere. The island exposes...

... Zone (000–020°). Combinations of these data with LANDSAT information reveal four shear bands along the margins of the Red Sea and one oblique to the Gulf of Suez. We have named the northern three Red Sea shear zones detected on the SIR-A data, the Brothers–Dead Sea Fracture Zone, the Zabargad Fracture...

... coastline. The integrated 2D and 3D modeling reveals the presence of high-density magnetic bodies that are located along the margin. The location of the present-day Zabargad transform fault zone is very well delineated in the computed crustal thickness maps, suggesting that it is associated with thin crust...

... of Zabargad (see page 81) but the isle’s description is on page 91. The only other “error” found was the color of peridot cut gems in the photo on page 93. The color seems very dark, almost an evergreen color, which is not typical of gem peridot. None of these trivial items detract from the intent of the book...
