Adamastor – an ocean that never existed?
Konopasek, Jiri; Cavalcante, Carolina; Fossen, Haakon; Janoušek, Vojtěch (Journal article; Peer reviewed, 2020)Existing models of tectonic evolution of the Neoproterozoic orogenic system rimming the shores of the South Atlantic Ocean (the Araçuaí–Ribeira–Congo and Dom Feliciano–Kaoko–Gariep belts) interpret the belts as subduction-related ... -
Comment to “Neoproterozoic magmatic arc systems of the central Ribeira belt, SE-Brazil, in the context of the West-Gondwana pre-collisional history: A review”
Fossen, Haakon; Meira, Vinicius T.; Cavalcante, Carolina; Konopásek, Jiří; Janoušek, Vojtěch (Journal article; Peer reviewed, 2021) -
A critical discussion of the subduction-collision model for the Neoproterozoic Araçuaí-West Congo orogen
Fossen, Haakon; Cavalcante, Carolina; Konopásek, Jiří; Meira, Vinicius T.; Trompette, Roland; Hollanda, Maria Helena B.M.; Paes de Almeida, Renato (Journal article; Peer reviewed, 2020)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 Patos-Pernambuco shear system of NE Brazil: Partitioned intracontinental transcurrent deformation revealed by enhanced aeromagnetic data
Fossen, Haakon; Harris, Lyal B.; Cavalcante, Carolina; Archanjo, Carlos José; Ávila, Carlos F. (Journal article; Peer reviewed, 2022)The Neoproterozoic-Cambrian (Brasiliano) intracontinental Patos-Pernambuco shear system is developed in Archean to Neoproterozoic crust, reactivating rift margins N of the São Francisco Craton. We here use enhanced ... -
Quartz textural analysis from an anastomosing shear zone system: Implications for the tectonic evolution of the Ribeira belt, Brazil
Conte, Thailli; Cavalcante, Carolina; Lagoeiro, Leonardo Evangelista; Fossen, Haakon; Silveira, C.S. (Journal article; Peer reviewed, 2020)Strain localization and influence of grain-size reduction processes were investigated from field and microstructural observations, and from quartz textural analysis using EBSD, in rocks deformed along an anastomosing network ... -
Reviewing the puzzling intracontinental termination of the Araçuaí-West Congo orogenic belt and its implications for orogenic development
Cavalcante, Carolina; Fossen, Haakon; Almeida, Renato Paes de; Hollanda, M.H.B.M.; Egydio-Silva, Marcos (Peer reviewed; Journal article, 2019)Palinspastic reconstructions suggest that the late Proterozoic–Cambrian Brasiliano/Pan-African orogenic belt in southeast Brazil and west Congo terminated northwards into an embayment within the São Francisco-Congo cratonic ... -
TitaniQ temperatures and textural analysis as a record of the deformation history in a major continental shear zone system, Borborema Province, Brazil
Cavalcante, Carolina; de Jesus Costa, Juliana; Lagoeiro, Leonardo; Fossen, Haakon; Lee, Amicia; Archanjo, Carlos; Vizeu, Roberto (Journal article; Peer reviewed, 2022)We combine quartz textural analysis with Titanium-in-quartz (TitaniQ) geothermometry to investigate the late stages of deformation in mylonitic rocks from the Sucuru dike swarm in the Borborema Province. The wide range in ...
