The present study investigates a paleo-estuary at the Doce River Delta, southeastern Brazil, through a multi-proxy approach that links palynology, diatoms, sedimentology and geochemistry analyses (i.e., Total C, Total N, δ13C and δ15N). These analyses, temporally synchronized with five radiocarbon ages, revealed environmental changes from marine to continental over the last ∼7550years. The studied...
High-resolution sedimentological, geochemical and pollen analysis on sediment core from the coastal plain of the Doce River, southeastern Brazil, revealed changes in the depositional system and vegetation caused by combined action of oscillations in relative sea-level (RSL) and sedimentary supply during the Holocene. Two main phases were discerned using sedimentary features, δ 13 C, δ ...
The dynamics, over the last 7500years, of a mangrove at Marajó Island in northern Brazil were studied by pollen and sedimentary facies analyses using sediment cores. This island, located at the mouth of the Amazon River, is influenced by riverine inflow combined with tidal fluctuations of the equatorial Atlantic Ocean. Herbaceous vegetation intermingled with rainforest dominates the central area of...
