Abstract
Neutron activation analysis was performed on aluvial soil samples from several sites on the floodplains of the Amazon River and its major tr ibutaries for trace elements determination. The spatial and temPoral v ariations of chemical composition of floodland sediments in the Amazon basin are discussed. No significant difference was found in trace ele mental distribution in the floodland soils along the Amazon main chann el. even after the source material has been progressively diluted with that from lowland draining tributaries. It was also seen that the ave rage chemical composition of floodplain soils compares well with that of the suspended sediments.
