Abstract

Hainan soils contain a mixture of material derived from in situ weathering of parent material plus atmospheric inputs dominated by continental dust. The AA. use Nd isotope geochemistry to evaluate the impact of continental dust on a chronosequence of Hainan soils. On the basis of the geomorphic stability sites, the AA. think that the decrease of dust inputs due to climate changes and the loss of dust due to weathering are the dominant loss mechanisms for dust and lead to underestimates of time-averaged dust deposition rates in the old sites. They calculate long term dust accretion rates to quantify the deposition. The results also underscore the potential for neodymium isotopes to constrain the origin of soils and paleosols
