Paleo-permeability in oceanic lithosphere inferred from vein mapping along the Wadi Haymiliyah of the Oman Ophiolite

Abstract To assess the permeability structure of the oceanic lithosphere, we analyzed the field-based vein distribution and geometry in the Wadi Haymiliyah area of the Oman ophiolite. The mineral-filled veins are a fossil record of fluid circulation, and we divided the veins into four categories: amphibole vein, epidote vein, prehnite vein, and serpentine vein. Amphibole and epidote veins are formed during high-temperature hydrothermal circulation near the oceanic ridge, while prehnite and serpe
