Abstract

This paper presents that the mean age of phytoliths and soil organic matter (SOM) in the uppermost 2.6 m of a latosol in central southern Brazil increases with depth in a regular, quantifiable fashion. The mean age of particles at each level results from a balance between continuous translocation and selective dissolution. The AA. then examine the reliability of paleovegetation records inferred from soil phytolith assemblages and SOM carbon-isotope analysis by comparison with pollen and charcoal data previously published. Finally, they reconstruct the movement of a boundary between forest and cerrado and its relation with paleofires during the late Holocene period
