註釋This report presents results from a multimedia geochemical study of several sites in the Abitibi greenstone belt of northeastern Ontario where known gold and base metal mineralization is covered by glaciolacustrine or glaciofluvial sediments. The objective was to determine whether the dispersion of elements in water-saturated overburden is sufficient to produce a detectable response at surface in water from drainage pathways, organic-rich media in drainage pathways, and A and B horizon soils. The report includes description of the sampling and analytical procedures, of the bedrock and surficial geology in the study area, and of the geochemical anomalies observed in sols, surface water, and organic streambank and peat media. The relationship between surface trace element geochemistry and mineralization is assessed and the dispersal mechanisms are discussed. The appendices include element frequency distributions.
