note an alluviation
event in the Argive Plain in the later Neolithic, (21) while Zangger et al.
This climatic transition is manifested in paleoecological records by rising lake levels, dune stabilization, partial melting of permafrost in lowland sites, increased alluviation
and hillslope erosion, and accumulation of soil organics (peat).
In contrast, the Rio Maranon carries a substantial load of clayey sediment which results in a more fertile floodplain due to greater alluviation
compared to that of the Negro.
A -15,000-year record of E1 Ninodriven alluviation
in Southwestern Ecuador.
Nevertheless, it is clear that much of the older archaeological record in this region either has been destroyed or deeply buried as a result of widespread alluviation
during the late Holocene.
