Amalgamating eastern Gondwana: The evolution of the Circum-Indian Orogens

TL;DR: For the Middle Ordovician period, the authors determined the most reasonable absolute paleoposition of the North China Block during the MiddleOrdovician: paleolatitude of approximately 16.6°S to 19.1°S and paleolongitude of about 10°W. The block was located between the Siberian Plate and Gondwana, close to the Siberian plate.

TL;DR: Granulite-facies metamorphism recorded in NE Mozambique is attributed to three main tectonothermal events, covering more than 1400 Ma from Palaeoproterozoic -early Neo-Palaeozoic time as discussed by the authors.

TL;DR: In this article, a review of petrological and geochronological data from Tanzania and northern Mozambique indicate that Ediacaran to Cambrian (600 and 500 Ma) subduction and collision events resulted to the reworking of the southern and eastern margins of the Tanzania Craton, the Orosirian Ubendian - Usagaran Belt, and the Cryogenian Moçambique Belt.

TL;DR: In this paper, the Sindreth Group exposed near Sirohi in southern Rajasthan, western India, is a volcanosedimentary sequence and Zircons from Sindreth rhyolite lavas and tuffs have yielded U-Pb crystallization ages of ~768-761.

TL;DR: Comparative geology suggests that the continents adjacent to northern, western, southern, and eastern Laurentia in the Late Proterozoic were Siberia, Australia-Antarctica, southern Africa, and Amazonia-Baltica, respectively.

TL;DR: The most important, rapid, and enigmatic changes in our Earth's environment and biota occurred during the Neoproterozoic Era (1000-540 million years ago; Ma).
