Soil weathering and accumulation rates of oxalate-extractable phases derived from alpine chronosequences of up to 1Â Ma in age

► Formation rates of pedogenetically formed oxyhydroxides were measured. ► These formation rates distinctly decreased with increasing soil age. ► After 1 Ma, about four order of magnitude lower rates were determined. ► Distinct time trends were observed for weathering indexes and elemental losses. ► The time trends could be modelled using a power function or an exponential decay.
