Scientific paper

A detailed U-Th-Pb isotopic study of two Archean basalts from two greenstone belts in the eastern Wawa Subprovince of the Canadian shield was carried out on samples that were either dissolved at once or leached in either 1N HNO3, 2N HCl, or 6N HCl. The abundances and isotopic compositions from these samples suggest that variable disturbances had occurred in both rock systems, which can be attributed to Pb mobility, particularly in the form of sulphide addition at various times, and, in one case, by recent Pb loss. The Pb isotopic compositions of the sulphides record late events which affected the greenstone terrains. The results also indicate that the sulphides and silicate rocks could have originated from a common source. The isotopic compositions of the basalt suggest that, in the Archean, both depleted and enriched mantle sources existed beneath the Wawa Subprovince.
