Tethys is the name of an ancient Greek goodness of the sea, and the term refers to the Mediterranean Sea. Geologically, Tethys is equivalent to the ancient Mediterranean Sea. It formed between the supercontinents of Laurasia and Gondwana, roughly along the Alps-Himalaya orogenic belt in southern Europe, and it extended from the Pyrenees, Apennines, Alps, Karpaty and Caucasus ranges to Asia Minor, the Hindu Kush Mountains, the Pamirs and the Himalayas. It then turned south through Myanmar, the Indo-China Peninsula and Malaysia, extended to Sumatra and Timor, and linked to the circum-Pacific Ocean area. Tethys might have existed as early as the Neoproterozoic and lasted through the Palaeozoic and Mesozoic to the early Neogene. The rocks of Tethys experienced large-scale uplift during the Alps-Himalaya orogeny and became the highest mountain system in the world. The existing Mediterranean Sea between Europe and Africa is the remnant of Tethys.
