Mangrove soils have peculiar chemical and physical conditions generated by the variable water salinity, cyclic tidal changes and intense biological activity that produce complex clay suites. In this study, the crystal-chemical characteristics of clay minerals from two mangrove soils were investigated in detail to further our understanding of the processes taking place. The two Brazilian mangroves...
The magnetic properties of peats from the Paraiba do Sul Valley (Sao Paulo State) Brazil have been studied in cores up to 6.4 m long with a basal radiocarbon age of 11,080 years BP. In general, the magnetic susceptibility is low, but is consistently higher near the bottom of the profiles. Anhysteretic remanence is surprisingly strong in comparison to other magnetic properties, and is attributed to...
