... of the southern massifs that resolve this problem. Sampling of a continuous section in Wadi Abyad reveals ENE magnetizations in the dike rooting zone at the top of the lower crust that change systematically downwards to NNW directions in underlying foliated and layered gabbros. This is consistent only...

... peridotites dominate the southern massifs of the Oman ophiolite. We focused on sections in Wadi Abyad (Rustaq Massif), at Somrah (Samail Massif), and in Wadis Khafifah and Nassif (Ibra Massif), where extensive lower-crustal exposures occur ( Fig. 1 ). These consist of (1) layered gabbros, with modal...
