Spatial analysis of Amazonian Dark Earth formation supports an anthropic origin at the Caldeirão site, Brazil
Linking anthropogenic burning activities to magnetic susceptibility
This study provides the first survey of Brazilian magnetic susceptibility (MS) data from varying archaeological and geological contexts, including open‐air sites, quartzite, and limestone rockshelters, and Amazonian dark earths. Our MS analyses associated with archaeological findings allow us to propose MS values as proxies of intense anthropogenic burning activities for archaeological sites with (i) systematic use of large hearth lit in the same…
Amazonian dark earths in the fertile floodplains of the Amazon River, Brazil
Amazonian dark earths (ADEs) are fertile soils created by pre-Columbian Amerindian societies of the Amazon Basin. However, it is still not clear whether these soils were produced intentionally to improve infertile Amazonian upland soils or if they resulted from the accumulation of organic matter from sedentary settlements. This study characterizes the ADEs found in the naturally fertile alluvial floodplains of the Amazon River in the Central Braz…
Commodity production as restoration driver in the Brazilian Amazon? Pasture re-agro-forestation with cocoa (Theobroma cacao) in southern Pará
The increasing demand for agricultural commodities is a major cause of tropical deforestation. However, pressure is increasing for greater sustainability of commodity value chains. This includes the demand to establish new crop plantations and pasture areas on already deforested land so that new forest clearing for agriculture is minimized. Where tree crops are planted as part of agroforestry systems on deforested land, this amounts to a form of …
Caracterização de um perfil de solo desenvolvido no sambaqui fluvial Moraes, município de Miracatu - SP
Escavações arqueológicas desenvolvidas no sambaqui fluvial Moraes, no município de Miracatu, SP, revelaram distintas camadas arqueológicas que resultaram na configuração monticular deste sítio. Com o objetivo de discutir o processo formativo deste sítio, foram realizadas análises físico-químicas do solo de dentro e de fora do mesmo para a compreensão das propriedades que podem ter contribuído para a caracterização das particularidades encontradas…
Anthropogenic soils in the Central Amazon
Amazonian Dark Earths (ADE), one of the best-known examples of anthropogenic (man-made) soils, are the result of Amerindian settlements in the pre-Columbian period. ADE are highly variable in terms of their size, shape, depth and physical and chemical make-up. Scholars tend to divide ADE into two categories: terra preta and terra mulata. The former are dark and highly fertile soils replete with ceramic shards, indicating former areas of habitatio…
Faeces deposition on Amazonian Anthrosols as assessed from 5β-stanols
Amazonian Dark Earths
Amazonian soils are almost universally thought of as extremely forbidding. However, it is now clear that complex societies with large, sedentary populations were present for over a millennium before European contact. Associated with these are tracts of anomalously fertile, dark soils termed terra preta or dark earths. These soils are presently an important agricultural resource within Amazonia and provide a model for developing long-term future s…
