The Midyan Basin represents a key tectono-sedimentary province formed during the separation of the Arabian and African plates. The evolution of the basin involved multiple stages of rifting, plate rotation, and seafloor spreading associated with the Red Sea and the Gulf of Aqaba–Dead Sea transform system. In northwestern Saudi Arabia, barite occurs mainly as vein- and cavity-filling mineralization within the Proterozoic basement and Tertiary sedimentary successions of the Midyan Basi. The barite occurs as vertical to subvertical veins, 0.1 to 2 m thick and extending up to ∼250 m in length, cutting the Early Miocene Musayr Formation. The veins trend predominantly NW–SE (≈300° NW and 120° SE; Fig. 3B) and are commonly sheeted and brecciated, filling fractures associated with northwest-trending faults. The barite displays a variety of textural features, including radiating lath-like, rosette, fibrous, and banded habits.
