ASSOCIAÇÃO ENTRE A ANÁLISE PALEOAMBIENTAL DA FORMAÇÃO MACACU, GRÁBEN DA GUANABARA (RJ), E A SEDIMENTAÇÃO CENOZÓICA NA MARGEM CONTINENTAL ADJACENTE (PARTE NOTE DA BACIA DE SANTOS)

This paper aims to analyze the relationship between Paleogene offshore sedimentation from Macacu Basin (Guanabara Graben, RJ - Brazil) and the intense synchronous progradation at offshore Santos Basin. Guanabara Graben system is divided in three main environments: distal alluvial fan (facies association I); debris flow influenced braided river (facies association II); and braided river with episodic over flow (facies association III) in the axial of this system. The analyze of ten multichannel 2D seismic section (6 dip, 4 strike) from contiguous continental margin at the southwester-most Macacu Basin edge shows the development of three depositonal sequences since Paloegene. The second sequence is characterized by an oblique progradational prism near the continental border related to the onshore graben. This correlation is supported by paleocurrent data from faices association III.
