- Summary:
- The soil maturity index I/sub s//FeO does not apply to either /sup 204/Pb/sub r/ or C/sub hyd/; both are directly correlated with the submicron Fe/sup 0/(I/sub s/) content. They act as an index of soil maturity which is independent of soil composition. In contrast to primordial Pb, radiogenic Pb is lost during soil maturation. Radiogenic Pb is present in mineral grains and may be lost by solar wind sputtering (or volatilization) and not resupplied. /sup 204/Pb coating grain surfaces acts as a reservoir to provide the /sup 204/Pb being extracted in the Fe/sup 0/ formation process. Venting or some other volatile source may replenish the surface /sup 204/Pb. 1 figure.
