We have selected 39 gabbro samples from the Wadi Gideah Transect sample suite, representing a full coherent crustal profile from the Moho transition zone (MTZ) to the dike/gabbro transition with an average sample spacing of about 120 m along the crustal depth. 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. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.934700"!
