Resumo: Peat sediments were observed during high tide occasions in the Praia Vermelha beach, urban area of the Rio de Janeiro city. They were studied to investigate possible environmental variations during the Quaternary Period. Palynological analysis was carried out comprising a time interval from ca. 4.520 À 80 to 4.270 À 60 years B.P. During this time the results obtained indicate that a restinga forest vegetation was sequentially dominated by a restinga bog vegetation. A great number of spores presenting corrosion/degradation damage, typical characteristics of exposition to the air, indicate that low quantity of water was disposable occasionally.

As análises palinológicas aplicadas a estes sedimentos, visando verificar variações ambientais que possam ter ocorrido durante o Período Quaternário, compreenderam o intervalo de tempo entre 4.520 - 4.270 anos A.P. Os resultados obtidos indicaram que durante o intervalo de tempo citado havia inicialmente o domínio de uma vegetação característica de mata de restinga que passou a ser dominada pela vegetação de brejo de restinga, sem intervenção marinha. A ocorrência de um grande número de esporos apresentando danos de corrosão/degradação por terem sofrido oxidação pela exposição ao ar, indica que ocasionalmente houve menor disponibilidade de água no local.Universidade Federal do Rio de Janeiro2014-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/697810.11137/2014_1_92_103Anuário do Instituto de Geociências; Vol 37, No 1 (2014); 92-103Anuário do Instituto de Geociências; Vol 37, No 1 (2014); 92-1031982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJporhttps://revistas.ufrj.br/index.php/aigeo/article/view/6978/5545Copyright (c) 2014 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBartholomeu, Robson LucasBarros, Marcia Aguiar deLopes, Marcel Rocha SoaresVilela, Claudia GutterresBarth, Ortrud Monika2017-01-23T22:42:35Zoai:www.revistas.ufrj.br:article/6978Revistahttps://revistas.ufrj.br/index.php/aigeo/indexPUBhttps://revistas.ufrj.br/index.php/aigeo/oaianuario@igeo.ufrj.br||1982-39080101-9759opendoar:2017-01-23T22:42:35Anuário do Instituto de Geociências (Online) - Universidade Federal do Rio de Janeiro (UFRJ)false
