All samples were taken at outcrops of fresh gabbro along the Wadi. The height above Moho (h.a.M.) was calculated with respect to the MTZ reference latitude of 22.9152N DD, assuming a generalized average dip of 28° for the layering of the lower gabbros in the Wadi Gideah area. The freshest and primary region of each hand specimen was cut into a block with a water-cooled diamond-blade saw, avoiding areas influenced by secondary weathering and hydrothermal overprint, and subsequently processed to a polished thin-section. We studied the thin-sections using a polarized light microscope to identify petrographic key parameters, which are presented here.58.501258.532622.826122.914Oman
