“…Devido a sinuosidade ativa dos rios Beni e Madre de Dios, os sítios arqueológicos mais antigos estão hoje provavelmente localizados acerta distância das ribanceiras e outros podem ter sido destruídos por completo pelas migrações dos canais. Mudanças nos cursos dos rios, por uma migração lateral de canal ou uma avulsão repentina, podem ter sido um dos fatores que levaram ao abandono dos sítios na Amazônia Ocidental (LATHRAP, 1968;PÄRSSINEN et al, 1996).…”

Este artigo visa apresentar uma síntese das pesquisas arqueológicas realizadas nos sítios com estruturas de terra em Riberalta e no estado do Acre, na Amazônia Sul-Ocidental. Os sítios nas duas regiões vizinhas foram comparados discutindo seus paralelos e diferenças. Os sítios bolivianos, sendo estruturalmente menos complexos, são interpretados como assentamentos permanentes, enquanto no Acre as estruturas de terra foram construídas principalmente para fins cerimoniais. A prática da engenharia de terra prevaleceu em Riberalta de 200 a.C. até o Período Colonial. No Acre, a tradição começou mais cedo, ca. 1200 a.C. As populações formativas que ocuparam estes sítios demonstram um sedentarismo emergente e desenvolvimento organizacional. No contexto do Acre os povos foram unidos por um sistema ideológico materializado na arquitetura das estruturas de terra geométricas.

“…Although our oldest peat initiation dates coincide broadly with the onset of this wet interval, some of the peat deposits have much younger basal ages (Lähteenoja et al, 2009b), indicating that peat formation was not determined purely by climate. Peat initiation may be controlled by the dynamic lateral migration of western Amazonian rivers, characterized by meandering and avulsion (Kalliola et al, 1992;Neller et al, 1992;Pärssinen et al, 1996), which have the potential to erode and bury peat deposits. Peat accumulation probably began when an area with waterlogged conditions was isolated from the immediate destructive influence of rivers.…”

“…The Ucayali has a highly dynamic meandering channel and a meander belt tens of kilometres wide; on the eastern side there are Quaternary fl uvial terraces that are probably of climatic and tectonic origin . In the central parts of the Ucayali sub-basin, major river avulsion occurred after the 1500s in an area of relative subsidence southeast of the city of Pucallpa in Peru (Kalliola et al 1992;Pärssinen et al 1996). This avulsion shifted the course of the Ucayali River closer to the Andes, leaving behind a large meander plain, and resulting in the submersion of one of its lowland tributary valleys, the currently blocked-valley lake Laguna Imiria.…”

Amazonia: Landscape and Species Evolution

The Amazon River system developed into its present form in a comparatively short period over approximately the last 10 million years. The western part of the drainage basin was mainly controlled by exhumation of the Andes. The Cenozoic Andean foreland consisted of a series of subsiding aggradational basins, interrupted by segments of basement (arches), which were particularly active during the Neogene. In this geodynamic landscape a system of highly instable rivers developed. During the Quaternary, landscape evolution was controlled by glacio-eustatic changes. The central to eastern part of the basin (i.e. the lower reaches of the AmazonSolimões River) was most affected by glacio-eustacy and the effect extended upstream beyond the halfway point of the continent. The present várzeas and the numerous associated ria lakes are an indication of incomplete infi lling of the palaeovalleys that were incised during the low-sea-level periods. In the Andean forelands, the soils in terra fi rme are highly variable due to their different sedimentation histories, parent materials and drainage conditions. The heterogeneity of the edaphic site properties infl uences the distribution patterns of the Amazonian biota, with highly specialized habitats occurring in the most extreme conditions. Denudation with deep alteration of the former aggradational plains in western Amazonia modifi es the forest ground with time; also in the Precambrian shields in northern and southern parts of Amazonia, forest soils have been altered by deep weathering under the hot and moist tropical climatic conditions of the region. In this chapter we describe in particular the evolution of the fl uvial landscapes in the Amazon drainage basin from the Miocene onwards, with particular emphasis on the Quaternary.
