Abstract

Studies of paleoenvironmental reconstruction (vegetation and climate) have continued to be developed in the Amazonian, Central, Northeast, Southeast and South regions of Brazil, in some locations using pollen grains deposited in lake and turf deposits, and in others, isotopes of carbon from the organic matter of the soil (OMS) and fragments of charcoal found in the soil, among other indicators. To reinforce the paleoenvironmental studies carried out up to the present in the Southeast region it is intended through this project, to develop comparative studies involving isotopic records of the OMS and plants, palinological studies in peateries and in mangrove swamps and with the possibility of associating it with antracological analysis, if there is found to be the presence of carbon fragment buried in the ground. Samples will be taken from the Serra do Mar State Park - Curucutu Nucleus, São Paulo (SP), and on the Ilha do Cardoso, south coast of the State of São Paulo.We will collect soil samples for physical, chemical and isotopic analysis of the OMS and also of 14C of the humin fraction of these soils. Equally, if found, we will sample fragments of carbon, wood and other buried vegetal remains in order, together with the humin, to establish the chronology of probable vegetational and climatic changes which occurred in the region in the last 20,000 years. Samples of turf and mangrove will be collected for palinological, isotopic analyses 14C dating. The integration of techniques and researchers should back up significantly the studies in vegetational and climate changes which occurred during the Late Pleistocene and Holocene in the Southeast region of Brazil and enable a multi and interdisciplinar approach.
