A critical discussion of the subduction-collision model for the Neoproterozoic Araçuaí-West Congo orogen
Fossen, Haakon; Cavalcante, Carolina; Konopásek, Jiří; Meira, Vinicius T.; Paes de Almeida, Renato; Hollanda, Maria Helena BM de; Trompette, Roland (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-22)The Neoproterozoic Araçuaí-West Congo orogen in Brazil and Congo represents a branch of the Brasiliano/Pan-African orogenic system that is considered to terminate northward into a confined cratonic environment defined by the horseshoe-shaped pre-Atlantic São Francisco-Congo craton. The prevailing interpretation is that this orogen formed as a result of 50 m.y. of subduction leading to a classical ... -
The role of Ediacaran synkinematic anatectic rocks and the late-orogenic charnockitic rocks in the development of the hot Araçuaí belt
Cavalcante, Carolina; Meira, Vinicius T.; Magalhães, Nivea; Hollanda, Maria Helena B.M.; Oliveira, Eurídice (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-13)The orogenic evolution of the hot Araçuaí belt is characterized by continuous magmatic activity, with magmas of different compositions recording a long-lived (∼630 to ∼530 Ma) tectono-thermal evolution in response to convergence between the Congo and São Francisco continents during the West Gondwana amalgamation. Geochemical data from the Carlos Chagas domain (CCD) and the Nova Venécia Complex (NVC), ...
