Semail (Samail) Ophiolite

Issued in 1990, this stamp commemorates the Semail (Samail) Ophiolite, one of the world's most significant geological formations, located in northern Oman. The Semail Ophiolite is renowned for exposing large sections of ancient oceanic crust and upper mantle above the Earth's surface, making it a site of exceptional scientific importance. Geologists from around the world have studied the formation to better understand plate tectonics, ocean floor geology, and the structure of the Earth's crust. By issuing this commemorative stamp, the Sultanate of Oman highlighted its unique geological heritage and recognized the international scientific significance of the Semail Ophiolite. The issue celebrated Oman's contribution to geological research and emphasized the importance of scientific study, natural heritage conservation, and international cooperation in advancing knowledge of the Earth's history and geological processes.
