Amphibolites are one of the major rock units in the Posht-e-Badam ophiolite that are formed by metamorphism of basalts. There are tow types of amphibolite in the Posht -e- Badam ophiolite: 1) amphibolites with intermediate plagioclase (first type), amphibole, plagioclase, quartz, sphene, ilmenite, apatite, sericite and epidote, 2) amphibolites with high content of anorthite (second type), amphi...

Fossil worm tubes of Cretaceous age preserved in the Bayda massive sulfide deposit of the Samail ophiolite, Oman, are apparently the first documented examples of fossils embedded in massive sulfide deposits from the geologic record. The geologic setting of the Bayda deposit and the distinctive mineralogic and textural features of the fossiliferous samples suggest that the Bayda sulfide deposit ...

Ophiolites are widely studied to unravel how new subduction zones form. They may contain crustal and mantle rocks that formed during juvenile stages of intra-oceanic subduction, modifying the pre-existing oceanic lithosphere within which started, in a magmatic arc upon maturation. Previous geochemical work on Cretaceous Andaman Ophiolite its metamorphic sole, located forearc Sunda zone south-ea...

Fault throw gradients create transverse folding, and this can influence accommodation creation sedimentary routing infill patterns in extensional half-graben basin. The Fanja basin (Oman) offers an excellent outcrop of alluvial fan succession displaying cyclical stacking basin-scale growth-fold patterns. These unique conditions allow for investigation fault-timing development related to fault-t...
