Previous issue date: 2013-08-29 / The proposal of this paper is to present direct data of paleosols of two sambaquis, Marambaia I e Figueira II located in the North Shore of Rio Grande do Sul. This research had it?s origin from an attempt to explore the sediment of these sites because they were different from the other ones within the constructive process that were verfified in those profiles. Samples of these sediments were taken to the laboratory submitted a fractionated subdivised and taken af to an oven with a temperature of 60?C during 24 hours. After this process these samples were sleved, processed and taken to a microscope. By using this methodology it was approach possible to visualize the micro particles and to supply information about the physical composition of such sediments. The results have shown phytoliths of grasses, sedges, pollen grains and also charred particles. As this paper's main objective was to fallow the visualization promote of micro structures, showing a part of that environment during the occupation, one can say that paper has achieved its goal. In the samples collected at Site Figueira II fungal spores were found. This kind of fungus because of this "obligatory symbiosis " need the presence of exudates root to emit hyphae, but it only occurs in dry environments. Places constantly affected by floods inhibit its development. The presence of these fungal spores suggests the occurrence of wet ground soils but not soaked. This information leads us to understand that the environment is getting stable where the Restinga starts to expand by about Holocenic cords. The presence of charred vegetable tissues were limited and may not be interpreted as being remains of campfire or daily human, but the increase these carbonized (charred) particles can indicate, the action of burned of origin anthropic. / A proposta deste trabalho ? apresentar dados diretos sobre os paleossolos de dois sambaquis, Marambaia I e Figueira II situados no Litoral Norte do Rio Grande do Sul. A pesquisa teve in?cio em uma tentativa de explorar o sedimento destes s?tios, pois estes se diferenciavam em meio ao processo construtivo evidenciado nos perfis. Foram coletadas amostras destes sedimentos; levadas ao laborat?rio; submetidas ao fracionamento; em seguida permaneceram no forno a 60?C durante 24 horas. Ap?s, as amostras foram peneiradas, processadas e levadas ao microsc?pio para observa??o de toda e qualquer micro informa??o. Ao utilizar a metodologia descrita, buscou-se fornecer informa??es sobre a composi??o f?sica destes sedimentos, e os resultados demonstraram fit?litos de gram?neas, ciper?ceas, gr?os de p?len, al?m de part?culas carbonizadas. Como o principal objetivo era promover a observa??o das microestruturas revelando uma m?nima visualiza??o do ambiente no per?odo da ocupa??o, conclui-se que o trabalho foi satisfat?rio. Nas amostras do S?tio Figueira, foram encontrados esporos de fungos. Este tipo de fungo por ser simbionte obrigat?rio necessita da presen?a dos exsudatos radiculares para emitir suas hifas. A presen?a destes esporos de fungos sugere a ocorr?ncia de solos um pouco ?midos, onde regi?es constantemente alagadas inibem seu desenvolvimento. Esta informa??o nos leva a compreender que o ambiente est? se estabilizando onde a Restinga come?a a se expandir por sobre os cord?es holoc?nicos. A presen?a de tecidos vegetais carbonizados foi limitada, n?o podendo ser interpretada como sendo restos de fogueira ou atividades humanas cotidianas, mas o aumento destas part?culas carbonizadas pode indicar a a??o de queimadas de origem antr?pica.
