Resumo: | The Highlands of the Rio de Janeiro (RSF) are composed of granitic gneiss, paragneiss and granite that are part of the Ribeira Belt. Their geological features were studied for over 50 years by authors who described orthogneisses and granites arranged in large overlapping tectonic sheaths. Tectonic domains and terranes were proposed for the Ribeira Belt, and the rocks of the RSF were included in the Oriental Terrane. The tectonic and magmatic evolution of the RSF begins in the Cryogenian with the installation of the magmatic arc of the Rio Negro Complex and sedimentation of the Italva, St. Fidélis and Bom Jesus do Itabapoana groups. During the Ediacaran collision of this arc with a passive margin the migmatitic leucogneisses of the Cordeiro Suíte were generated. At the collisional ending the calc-alkaline magmatic Serra dos Órgãos Suíte was produced. At the end of evolution, tectonic exhumation and tectonic collapse was coeval with the intrusion of Cambro-Ordovician granites of the Nova Friburgo Suíte. |

Seus aspectos geológicos são estudados há mais de 50 anos por autores que descreveram ortognaisses e granitos dispostos em grandes escamas tectônicas superpostas. Dominios e terrenos tectônicos foram propostos para a Faixa Ribeira, sendo as rochas da RSF incluidas no Terreno Oriental. A evolução tectônica e magmática da RSF se inicia no Cryogeniano com a instalação do arco magmático do Complexo Rio Negro e sedimentação das rochas dos grupos Italva, São Fidélis e Bom Jesus do Itabapoana. Durante a colisão Ediacarana deste arco com uma margem passiva teria ocorrido metamorfismo geração dos gnaisses migmáticos da Suíte Cordeiro. Seguiu-se à colisão o magmatismo calci-alcalino da Suíte Serra dos Órgãos. Ao final da evolução, a exumação tectônica do conjunto teria originado um colapso tectónico, com a consequente intrusão dos granitos pós-colisionais da Suíte Nova Friburgo durante o Cambro-Ordoviciano.Universidade Federal do Rio de Janeiro2012-12-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/694310.11137/2012_2_140_151Anuário do Instituto de Geociências; Vol 35, No 2 (2012); 140-151Anuário do Instituto de Geociências; Vol 35, No 2 (2012); 140-1511982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJporhttps://revistas.ufrj.br/index.php/aigeo/article/view/6943/5510Copyright (c) 2012 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessTupinambá, MiguelTeixeira, WilsonHeilbron, Monica2017-01-23T22:34:48Zoai:www.revistas.ufrj.br:article/6943Revistahttps://revistas.ufrj.br/index.php/aigeo/indexPUBhttps://revistas.ufrj.br/index.php/aigeo/oaianuario@igeo.ufrj.br||1982-39080101-9759opendoar:2017-01-23T22:34:48Anuário do Instituto de Geociências (Online) - Universidade Federal do Rio de Janeiro (UFRJ)false |
