Gondwana was formed by the accretion of several cratons (large stable blocks of the Earth's crust), beginning c. 800 to 650 Ma with the East African Orogeny, the collision of India and Madagascar with East Africa, and culminating in c. 600 to 530 Ma with the overlapping Brasiliano and Kuunga orogenies, the collision of South America with Afric...
Gondwana – południowy superkontynent, istniejący w paleozoiku i na początku mezozoiku oraz ponownie pod koniec mezozoiku i na początku kenozoiku. Jego nazwa pochodzi od północnego regionu Indii , a termin ten wprowadził jako pierwszy Eduard Suess , który stwierdził m.in. zaskakujące podobieństwo wymarłej flory glossopterisowej na ...
Gondwana was a supercontinent that existed from about 550 to 180 million years ago. It was formed when several smaller continents, including what is now South America, Africa, India, Australia, and Antarctica, collided and merged together.
In this study, crustal structures are imaged by modeling receiver functions to understand the differences in the nature of the crust that was once part of Precambrian Gondwanaland.
1 wrz 2023 · Estimated Moho depth is highlighted in a Gondwana reconstruction. Secular trend shows increasing crustal thickness towards end of Archean. We present a global study of the crustal structure with emphasis on the twelve main cratons of the earth.
1 lis 2013 · From its unification in the Late Neoproterozoic to its amalgamation with Laurussia in the Carboniferous to form Pangea, Gondwana was the largest unit of continental crust on Earth for more than two hundred million years.
14 paź 2024 · Gondwana, ancient supercontinent that incorporated present-day South America, Africa, Arabia, Madagascar, India, Australia, and Antarctica. It was fully assembled by Late Precambrian time, some 600 million years ago, and the first stage of its breakup began in the Early Jurassic Period, about 180 million years ago.
