Gondwana - Wikipedia

CAMP covered more than seven million square kilometres over a few million years, reached its peak at c. For example, some Palaeozoic terranes and microcontinents that now make up Central Asia, often called the "Kazakh" and "Mongolian terranes", were progressively amalgamated into the continent Kazakhstania in the Late Silurian.

Whether these blocks originated on the shores of Gondwana is not known. Precambrian rocks from gondwana flora Iberian Peninsula suggest it too probably formed part of core Gondwana before its detachment as an orocline in the Variscan orogeny close to the Carboniferous—Permian boundary.

This process can be divided into three phases of rifting along Gondwana's northern margin: These gondwana flora accreted to Asia during Late Devonian and Permian.


The Early Permian opening of the Neo-Tethys Ocean along this margin produced a long series of gondwana flora, many of which were and still are being deformed in the Himalaya Orogeny.

From Turkey to north-eastern India: The break-up was the result of one of the Earth's most extensive large igneous provinces c. Gondwana began to break up in the early Jurassic following the extensive and fast emplacement gondwana flora the Karoo-Ferrar flood basalts c.

Before the Karoo plume initiated rifting between Africa and Antarctica, it separated a series of smaller continental blocks from Gondwana's southern, Proto-Pacific margin along what is now the Transantarctic Gondwana flora During the initial break-up in the Early Jurassic a marine transgression swept over the Gondwana flora of Africa covering Triassic planation surfaces with sandstonelimestoneshalemarls and evaporites.

The Indian and Australian plates merged c. East Gondwana then began to break up c. Separation between Australia and East Antarctica began c.

A shallow gondwana flora developed over the South Tasman Rise during the Early Cenozoic and as oceanic crust started to separate the continents during the Eocene c.

The opening of the South Atlantic Ocean divided West Gondwana South America and Africabut there gondwana flora a considerable debate over the exact timing of this break-up. Rifting propagated from south to north along Triassic—Early Jurassic lineaments, but intra-continental rifts also began to develop within both continents in Jurassic—Cretaceous sedimentary basins; subdividing each continent into three sub-plates.

From there rifting propagated northward gondwana flora the Late Jurassic c. At Brazilian latitudes spreading is more difficult to assess because of the lack of palaeo-magnetic data, but rifting occurred in Nigeria at the Benue Trough c.


North of the Equator the rifting began after Such kind of subduction is held responsible not only for the intense contractional deformation that different lithologies were subject to, but also the uplift and erosion known to have occurred from the Late Cretaceous onward. Gondwana flora the Cenozoic the orogen resulted in the construction of the Tibetan Gondwana flora between the Tethyan Himalayas in the south and the Kunlun and Qilian mountains in the north.

A rift between the two developed but remained an embayment until the Eocene-Oligocene boundary when the Circumpolar Current developed and the glaciation of Antarctica began. The opening of the Tasman Gateway at the Eocene-Oligocene boundary gondwana flora Ma resulted in abrupt cooling but the Oligocene became a period of high rainfall with swamps in southeast Australia.

During the Miocene a warm and humid climate developed with pockets of rainforests in central Australia but before the end of the period colder and drier climate severely reduced gondwana flora rainforest. A brief period gondwana flora increased rainfall in the Pliocene was followed by drier climate which favoured grassland.

Since then the fluctuation between wet interglacial periods and dry glacial periods has developed into the present arid regime. Australia has thus experienced various climate changes over a 15 million gondwana flora period with a gondwana flora decrease in precipitation.

This, together with the reactivated Iceland plumecontributed to global warming.
