The Amazon is the largest drainage basin on Earth and contains a wide variety of abiotic
landscape features. In spite of this, the geodiversity in this basin has not yet been objectively …

The evolution of orogenic systems is a function of their overall tectonic context, and global
reconstructions therefore provide a crucial framework for understanding the geodynamic …

Western Gondwana amalgamated by collision of continental blocks that did not form prior
conjugated margins (extroversion), and by typical Wilson cycles, when continental blocks …

Lenses of retrogressed eclogites occur in a 100 km wide zone of the Nyong Complex, a
remnant of the Eburnian-Transamazonian orogen, marking a Palaeoproterozoic suture …

Abstract The Nyong Complex and the Yaoundé Group represent two crustal sequences of
West Gondwana in Cameroon. We use U-Pb zircon geochronology on meta-sedimentary …

High-to ultrahigh-pressure metamorphic assemblages consisting of garnet-omphacitic
clinopyroxene bearing mafic rocks have been identified within the Paleoproterozoic Nyong …

Abstract Assembled during the Rhyacian-Orosirian boundary, the Congo-São Francisco
palaeocontinent remained linked by a continental bridge from ca. 2 Ga to the Atlantic Ocean …

Abstract The Minas-Bahia orogeny juxtaposed Archean crustal fragments and
Paleoproterozoic magmatic arcs to form the São Francisco-Congo Paleocontinent by the …

The southern portion of the São Francisco Palaeocontinent in Brazil is denoted by Archean
nuclei and Paleoproterozoic magmatic arcs that were amalgamated during Siderian to …
