Thallium isotopic fractionation in soil: the key controls

Popis výsledku v původním jazyce

We studied the key geochemical and mineralogical factors that could affect the fractionation of stable thallium Tl isotopes in soil. A set of grassland soil samples enriched in geogenic Tl in combination with selected Tlcontaining mineral materials from the Czech Republic Kluky were investigated for this purpose.Furthermore, our results displayed a clear relationship between the Tl isotopic fractionation degree and the Mn oxide soil concentration, as derived from the oxalate extractable data. A combination of soil and mineralogical considerations suggests that 205Tl enrichment in respective soil samples is also partly due to the Tl present in micaceous clay minerals, mainly illite, which is the predominant pedogenic Tl host phase. In line with our previous results, this Tl behavior can be inferred from systematic Mn oxide degradation and the associated Tl enriched in 205Tl cycling in the studied soils and thus, presumably in the redoximorphic soils in general.
