Stable Cu isotope fractionation in soils during oxic weathering and podzolization
Moritz Bigalke (1,2), Stefan Weyer (2), Wolfgang Wilcke (3)
Copper stable isotope ratios are fractionated during various biogeochemical processes and may trace the fate of Cu during long-term pedogenetic processes. We assessed the effects of oxic weathering (formation of Cambisols) and podzolization on Cu isotope ratios (d65Cu). Two Cambisols (oxic weathered soils without strong vertical translocations of soil constituents) and two Podzols (soils showing vertical translocation of organic matter, Fe and Al) were analyzed for Cu concentrations, partitioning of Cu in seven fractions of a sequential extraction and d65Cu values in bulk soil.
