Title: Lanthanides in the study of lithologic discontinuity in soils from the Piracicaba river basin
Abstract: This study was designed with the objective of using lanthanides to confirm the occurrence of lithologic discontinuities, formerly highlighted by morphological and mineralogical studies and recognized by field evidence, in three soil profiles from the Piracicaba river basin, Brazil. Comparison of lanthanide concentrations in the horizons and underlying rocks indicated the presence of allochthonous soils. Application of principal component analysis to the measured elements yielded well-defined segregation into groups with cumulative variances higher than 90% for the first two components. Lanthanides were confirmed as versatile indicators to corroborate parent material discontinuities for the soil profiles studied.
