Abstract

Peat sediments were observed during high tide occasions in the Praia Vermelha beach, urban area of the Rio de Janeiro city. They were studied to investigate possible environmental variations during the Quaternary Period. Palynological analysis was carried out comprising a time interval from ca. 4.520 À 80 to 4.270 À 60 years B.P. During this time the results obtained indicate that a restinga forest vegetation was sequentially dominated by a restinga bog vegetation. A great number of spores presenting corrosion/degradation damage, typical characteristics of exposition to the air, indicate that low quantity of water was disposable occasionally.
