Dynamics of production and accumulation of phytolith assemblages in the Restinga of Maricá, Rio De Janeiro, Brazil

“…The vegetal cover in restinga occurs as a mosaic and it is found on beaches, sandy barriers, dunes and depressions, with (according to the successional stage) herbaceous, shrub and tree strata, the latter being more internalized (CONAMA, 2002). Araújo and Henriques (1984) Although several studies have contributed to the knowledge on the formation and evolution of the Maric a coastal plain (Lamego, 1940;Muehe, 1984;Perrin, 1984;Ireland, 1987;Muehe and Corrêa, 1989;Turcq et al, 1999;Pereira et al, 2003;Pereira, 2009;Silva et al, 2014a, b) there are still gaps in understanding the environmental conditions under which this evolution has proceeded. Studies aimed at the reconstruction of palaeoenvironments based on diatoms (Ireland, 1987) and foraminifera (Bomfim et al, 2010;Bruno, 2013) were conducted on sediments collected on the coastal plain of Maric a in order to understand the geological evolution of this coast.…”
