Primeros estudios micromorfológicos en sambaquís brasile？os (sitio Jabuticabeira II, Estado de Santa Catarina)

in this note, preliminary results from the micromorphological study of the fish mound that covers the jabuticabeira ii sambaquí site, developed within the interdisciplinary research project sambaquis e paisagem, are presented. microstratigraphic analyses enabled the identification of anthropic pre-depositional processes that participated in the formation of this large structure, related to the burning and transport of mineral and organic material (terrigenous sand and charcoal) and inorganic residues of biological origin (bones, phytoliths, diatoms and siliceous aggregates). the effects of post-depositional alterations over these particles can be observed through dissolution traces in bone and the formation of a fine mineral material of phosphatic composition. the articulation of the evidence confirms the complex combination of activities and alteration processes involved in the formation of sambaquí sites, which transcends traditional functional dichotomies.
