Dr. Afifi’s Arabian Plate Geology Research Group (APG) covers a wide range of topics within Earth Science, with specialization in the stratigraphy, structure and tectonics of the Arabian Plate and the Red Sea. The practical aspects of their research include conventional carbon dioxide sequestration in saline aquifers, carbon dioxide mineralization in mafic and ultramafic rocks, conventional and low enthalpy geothermal systems, underground gas storage, and mineral resource potential. The APG collaborates with other research groups worldwide and at KAUST, integrating stratigraphy, structural geology, minerology, petrology, geochemistry, geophysics and biostratigraphy to understand Earth systems. ​
