Sedimentological Sectorization of An Estuarine System In A Regressive Coast, Southeast Brazil

Alex Evaristo Da Silva, Valéria Da Silva Quaresma, Alex Cardoso Bastos

Abstract

Multivariate statistical Previous HitanalysisNext Hit can be applied in order to group sediments with similar characteristics and be an important tool for the interpretation of Previous HitsedimentaryNext Hit facies for a given depositional environment. This study investigates the use of multivariate Previous HitanalysisNext Hit to produce a sectorization of an estuarine system located along a regressive coast (Espírito Santo, southeast Brazil). Results of cluster Previous HitanalysisNext Hit and principal component Previous HitanalysisNext Hit were compared to qualitative sediment interpretation based on well-known sediment classifications. Multivariate Previous HitanalysisNext Hit defined four distinct Previous HitsedimentaryNext Hit groups for the estuarine and adjacent inner shelf system. These groups reflect distinct Previous HitsedimentaryNext Hit facies found along the system: inner estuarine facies, outer estuarine facies, fluvial–coastal facies, and shelf facies. This sectorization is used to propose a Previous HitsedimentaryTop facies model for the system. Sedimentological variables used in the sectorization were shown to be good indicators of depositional environments, indirectly expressing the hydrodynamic energy.
