Geochemical behaviour of Ni, Cr, Cu, Zn and Pb in an Andosol–Cambisol climosequence on basaltic rocks in the French Massif Central

摘要: Abstract The objective of this study is to identify parameters influencing trace elements (TE) vertical distributions in an Andosol–Andic Cambisol climosequence. In order understand processes involved the current distribution from basaltic rocks associated soils, six pedons developed on Tertiary massive formations, located at similar position hill-slopes, submitted same wet mountainous climate but under various microclimatic conditions (altitude and annual rainfall), were considered. studied soils are andic rich organo–metallic complexes. Two different quantitative methods used compare geochemical major elements, both being calculated with Ti as invariant element: isovolumetric mass balance enrichment factors. Anthropogenic, pedogenetic, microclimatic, inherited factors discriminated. Anthropogenic influences pointed out for K two Pb all sites. Distributions other TE affected by discontinuities between underlying soil horizons. Zinc Cu controlled organic matter whereas Cr Ni influenced pedogenetic processes. Results emphasize relative element immobilization temperate climate.
