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

TL;DR: In this article, geochronological and geochemical data for gabbros of the Imorona-Itsindro suite from the Ambatondrazaka area in east-central Madagascar were presented.

TL;DR: In the country of Ethiopia, geosites such as the Tis Isat Falls on the Blue Nile, the lakes of the Rift Valley and even such iconic sites as the Dallol geothermal area are endangered as discussed by the authors.

TL;DR: In this paper, the authors investigated younger granitic rocks with very low contents of compatible elements such as Cr, Ni, and Co; and high contents of incompatible elements, such as Zr, and large ion lithophiles such as Sr, especially in the El Sela shear zone, which is invaded by quartz ENE-WSW veins associated with hydrothermal alteration accompanied by radioactive mineralization.

TL;DR: The Cauvery suture zone (CSZ) in southern India has witnessed multiple deformations associated with multiple subduction-collision history, with incorporation of the related accretionary belts sequentially into the southern continental margin of the Archaean Dharwar craton since Neo-Archean to Neoproterozoic.

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).
