Abstract

Research was conducted to establish the genetic relationship between soil color patterns and natural drainage characteristics in a hydrosequence of Oxisols formed in Tertiary/Quaternary sediments of the Cerrado (Savanna) Region of the Central Plateau of Brazil. Stratigraphic, geomorphic, and pedogenic evidence supports the hypothesis that soils having reddish hues and codominant hematite and goethite Fe mineralogy formed in a prior environment, then underwent changes in Fe oxide mineralogy in response to changes in hydrology brought about by landscape evolution and climate change. -from Authors
