- Tethyan Trench
The Tethyan Trench was an ancient
oceanic trenchthat existed in the northern part of the Tethys Oceanduring the middle Mesozoicto early Cenozoic eras.
The Tethyan Trench formed when the
Cimmerian Platewas subducting under eastern Laurasia, around 200 million years ago, in the Early Jurassic. The Tethyan Trench extended at its greatest during Late Cretaceousto Paleocene, from what is now Greeceto the Western Pacific Ocean. Subduction at the Tethyan Trench probably caused the continents Africaand Indiato move towards Eurasia, which resulted in the opening of Indian Ocean. When the Arabian and Indian plates collided with Eurasia, the Tethys Ocean and the trench closed. Remnants of the Tethyan Trench can still be found today in Southeastern Europeand southwest of Southeast Asia.
