Variação do nível do mar com base na análise organofaciológica de um testemunho do talude continental recente da bacia de Campos, RJ, Brasil

Abstract

Um total de 85 amostras coletadas em um testemunho de sondagem correspondente ao poco GL-77 localizado no talude continental da Bacia de Campos foram analisadas por tecnicas microscopicas (palinofacies) e organogeoquimicas (COT) fornecendo informacoes sobre a composicao orgânica da secao sedimentar analisada. A variacao organocomposicional encontrada nesta secao sedimentar pode ser um reflexo das oscilacoes do nivel do mar e mudancas climaticas que influenciam tanto na producao, transporte e preservacao quanto no suprimento e sedimentacao da materia orgânica no talude continental recente da Bacia de Campos. Para a caracterizacao paleoambiental da sucessao estudada, utilizou-se o diagrama ternario confeccionado a partir dos dados de abundância relativa dos tres grupos principais de materia orgânica que contem a definicao de nove paleoambientes baseados nos dados de palinofacies marinha. Atraves destes diagramas foi possivel tracar a curva do nivel relativo do mar baseado nas tendencias proximais-distais durante a sedimentacao dos componentes orgânicos particulados. Observou-se uma tendencia geral de transgressao marinha marcada por pequenos ciclos de rebaixamento/elevacao do nivel relativo do mar em virtude das variacoes do influxo sedimentar, reflexos estes das flutuacoes climaticas do Quaternario.
