Full textSix soils from the French Massif Central, submitted to different microclimatic environments, have been studied in order to determine the distribution and speciation of metallic trace elements (MTE) in the solid fraction of soils developed on weathered basalts and basanites. The tertiary basaltic rocks, and their subsequent developed soils, present high Cr (248-455 mg/kg) and Ni (126-237 mg/kg) contents. These soils are all andic soils, rich in organo - complexes but presenting no allophane. Three different approaches were combined to study the fate and the mobility of the MTE during supergene alteration. The mineralogical study of the unweathered rocks pointed out that MTE are present in the chromiferous spinels, the titanomagnetites and in the ferromagnesian silicates (forsterite and augite). The hydrolysis of the ferromagnesian silicates as well as the spinels resistance to alteration are the two main parameters respectively controlling the released of the MTE and their retention in clays associated to the authigenic iron oxides. Isovolumic balance and enrichment factor are the two quantitative methods carried out to evidence the pedological and lithological roles of these parameters involved in the MTE distribution in the three soils developed on basalts. This study confirmed the mineralogical control on the Cr and Ni distribution whereas the Cu and Zn distribution is related to organic matter and organo - minerals complexes. Despite the alteration strength of the mineralogical carriers, Cr and Ni tend to be partially released from the leaching of andosols in colder and higher rainfall conditions on the contrary to the andic cambisols environments where Cr and Ni are preserved. The organic components role is evidenced by the immobilisation of Cu and Zn whereas the major elements (Na, Mg, Ca, Si) are highly released. The selective extractions confirmed the main association of Cu with the soil organic components. This study highlight the low potential mobility of the MTE in mountainous temperate climate on the contrary to previous works carried out in warmer climate environments
