Abstract

Archaeological Black Earth (TPA) has a high carbon content, but the reason for such a balance is still uncertain. Characterization and relationship of iron oxides of clay soils with organic matter content can assist in building future scenarios of climate change, providing information that support decision-making strategies for mitigation and adaptation. The present work aims to characterize the iron oxides in the clay fraction of the Archaeological Land Black southern state of Amazonas. Trenches will be open 8 TPA in different locations in southern state of Amazonas. These trenches are described, and samples are sent to the laboratory for chemical analysis and subjected to x-ray diffraction (XRD). The results will be analyzed based on current literature and may assist in understanding the relationship between organic carbon and iron oxides in these Lands Archaeological. (AU)
