The first occurrence of Mesoproterozoic carbonatite in the Rio de la Plata Craton – RDPC indicates extensional event prior to the opening of the Charrua Ocean. Nd-Sr-Hf Isotopic and U-Pb on zircon geochronological data are presented for the Tres Es

Extruding the Borborema Province (NE-Brazil): a two-stage Neoproterozoic collision process

We propose that the development of the Borborema Province from 620 to 570 Ma resulted from two discrete collisional events. Collision I, along the West Gondwana Orogen on the west side of the Province, took place at c. 620–610 Ma as the result of c

Previous studies have proposed that a major suture resulted from the collision between the Amazonian and Sao Francisco-Congo cratons during the Cambrian, following the closure of a supposed Clymene Ocean. The proposal tentatively located this ocean a

Geochemistry and 207Pb/206Pb zircon ages of granitoids from the southern portion of the Tamboril–Santa Quitéria granitic–migmatitic complex, Ceará Central Domain, Borborema Province (NE Brazil)

The Tamboril–Santa Quiteria Complex is an important Neoproterozoic granitic–migmatitic unit from the Ceara Central Domain that developed from ca. 650 to 610 Ma. In general the granitoids range in composition from diorite to granite with predomina

International audience; The deeply eroded West Gondwana Orogen is a major continental collision zone that exposes numerous occurrences of deeply subducted rocks, such as eclogites. The position of these eclogites marks the suture zone between collidi
