Melt impregnation forms isotropic gabbro in the Oman ophiolite Moho transition zone. We measured crystallographic fabric for transition from isotropic to layered gabbro. Olivine fabric evolves from planar to [001] (010)-magmatic to [100] (010)-HTplastic. We deduce that gabbro layering originates from shear caused by host mantle flow. Isotropic stage means melt …
