Estudo da distribuição dos sedimentos no fundo do Estuário de Macuse

Abstract

The presente research had as main objective to analyze the sediment distribution in the bottom of the Macuse Estuary, To achieve the objective, eighteen (18) bottom sediment samples were collected through a bottom sampler designed at ESCMC-UEM. Using the screening and pipetting techniques, the samples were submitted to x-ray diffractometer mineralogical analysis to identify the sediment types where three sediment types were identified: clay, sand and silt. In general, the clay particle size class is the most predominant and presents the highest percentage, the percentages vary at each point or season. With the aid of a statistical parameter the average clay is 0.3892 with greater variability and secondly the silt with an average of 0.3122 and sand last with an average of 0.2986, this is probably due to the fact that the estuary is mostly made up of fine sediment with a reduced particle size class.
