The Afro-Eurasian landmass, which presently occupies more than 57% of the planet’s total land area, closely fits the modern definition of supercontinents. The continental collision between the Indian and Eurasian plate is one of the world's most renowned and most studied convergent systems. Pada akhir era Paleozoikum , Euramerica (saat akan membentuk Laurasia) bertabrakan dengan Gondwana sehingga mengakibatkan terbentuknya Superbenua Pangaea . Stage 1 (320-286 Ma, Late Carboniferous) is the stratigraphic lacuna that resulted from the high-standing Pangean platform that initially blocked the escape of heat from the interior. Thus, all Gondwana-derived microcontinents seem to share a significant acceleration during their northward motion. Asia, Polynesia and Madagascar. (298. Nearly 300 million years ago, the geography of the Earth was drastically different than it is today. ranes that now comprise portions of North America and Eurasia. However, many mechanisms remain.

[3] In the Early Cretaceous, the separation between Greater India (referring to the original extent of continental India, including the part now deformed in the Eurasia-India collision) and East Gondwana created the seafloor offshore East Antarctica (Figure 1) and West Australia (Figure 2), which were then a continuous continental block. The horizontal velocity change with depth is progressive. . 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). Several megafaunal species were extirpated from Eurasia, but persist today elsewhere, including the hippopotamus, muskox, and spotted hyena (Fig. 0 2003 International Association for Gondwana Research, Japan. The ensuing drift and dispersal of East Gondwana, initiatingWebConvergence between Gondwana and Eurasia is simulated by injecting continental lithosphere either symmetrically on both sides (Gondwana and Eurasia) or on one of them only. The collision between Laurasia and Gondwana during the Late Devonian-early Permian was a key event in the amalgamation of Pangaea and resulted in the destruction of the Rheic Ocean and the. 350 Ma, while the source of. Avalonia was a microcontinent in the Paleozoic era. and was the continents of Africa, South America, Australia, and Antarctica. The International Symposium on the Assembly and Break-up of Rodinia and Gondwana, and Growth of Asia was held in October 2001 in Osaka, sponsored by IGCP. In Figure 3b, we compare this latitudinal drift history of the EQT against paleolatitude curves for Eurasia, the Tarim Block (TB) and India (Gondwana), as computed for the same reference location (Table S6 in Supporting Information S1).
