『Abstract
At Niquelandia(最初のaの頭に^), Cr extracted from
the soil (5,000-9,300 mg.kg-1) is likely the result
of the Cr-bearing Fe-oxides compared to the Cr-spinels, showing
that low Cr-containing minerals present in the dunite (enstatite,
olivine and clay minerals) have been completely dissolved. The
chromites, accumulated inside soil profiles, have undergone chemical
weathering, leading to a Cr enrichment during soil genesis. Traces
of dissolution inside the soil chromites suggest that they can
be slowly weathered. In this case chromites could represent a
diffuse source of available Cr(III) within the soil profiles.』
