Structural Re-orientation of Magmatic Fabrics and Layering in the Lower Oceanic Crust: Hole GT1, Wadi Tayin Massif, Samail Ophiolite
… thesis aims to re-orient borehole images of layered gabbros sampled beneath Hole GT1 in the Wadi Tayin massif of the Oman ophiolite by the Oman Drilling Project to better constrain models of crustal accretion. The gabbro glacier model proposes that crystallized basalt flows down and away from …

The Sheeted Dyke-Gabbro Transition Zone: the Key to Unravelling the Palaeomagnetic Record of the Oman Ophiolite
… upper mantle peridotites, lower crustal gabbros, and upper crustal sheeted dykes and lava flows. Previous palaeomagnetic studies have suggested that the southern massifs of the ophiolite were affected by a large-scale remagnetization event during emplacement, which completely replaced …

Deciphering the signature of fluid/rock reactions in the lower oceanic crust: The Oman ophiolite analogue
… intervals throughout the whole section of layered gabbros. This study recognizes two main categories and a further 7 sub-categories of deformation, showing a range of mineral assemblages and variable chemical composition. The time-integrated record of fluid circulation reveals that …
