Association of Post-Barreiras and Barreiras Formation strata and influence on soil genesis, Southern Bahia – Brazil [PDF]

Revista Brasileira de Ciência do Solo, 2020
The term Post-Barreiras is a definition for sediments above the deposits of the Barreiras Formation, and the genesis of soils in these environments must be related to sedimentary deposition.

Spodosols pedogenesis under barreiras formation and sandbank environments in the south of Bahia [PDF]

Revista Brasileira de Ciência do Solo, 2010
Morphologically differentiated Spodosols usually occur in the Coastal Plain of the South of Bahia and North of Espírito Santo. They are found in profiles known as "muçungas", i.e. sandy soils that accumulate water. In these areas, two kinds of Spodosols, different from those in the Restinga area, can be found: Spodosols with E albic horizon (white ...

Genesis and variation spatial of Podzol in depressions of the Barreiras Formation, northeastern Espírito Santo State, Brazil, and its implications for Quaternary climate change [PDF]

Journal of South American Earth Sciences, 2020
Variations in relief associated with pedogenetic processes promote different intensities in weathering of sediments of the Barreiras Formation and may thus lead to the formation of different soil types, like Podzols, Acrisols and Ferralsols. The Podzols of tropical regions contain important information on climate and vegetation changes that occurred ...
