The continental collision between the Indian and Eurasian plate is one of the world's most renowned and most studied convergent systems. The second, major phase in the break-up of Pangaea began in the Early Cretaceous (150-140 million years ago), when the minor supercontinent of Gondwana separated into four multiple continents (Africa, South America, India, and Antarctica/Australia). Antes de Pangeia, o nome Gonduava (ou Gondwana) já havia sido proposto. The Tethyan evolution may be simplified as many continents rifting away from Gondwana and then continuously drifting towards the Eurasia, finally colliding and accreting onto the southern Eurasia. Laurasia Today . Abstract SE Asia comprises a collage of Gondwana-derived continental blocks assembled by the closure of multiple Tethyan and back-arc ocean basins now represented by suture zones. The name Laurasia combines the names of Laurentia and Eurasia. The name "Pangaea" is derived from Ancient Greek pan ( πᾶν, "all, entire, whole") and Gaia or Gaea ( Γαῖα, " Mother Earth, land").
