AbstractThe western part of the Bathurst-Jacquet River district, in which the geochemical survey described in this report was carried out, is underlain by folded and faulted Ordovician, Silurian, and Devonian sediments and volcanics and four granitic bodies. The eastern part is underlain by flat-lying to gently-dipping Pennsylvanian sandstones and shale s. The principal deposits in the district are massive, vein, and disseminated deposits containing essentially iron, zinc, lead, and copper sulphides. Molybdenite occurrences are associated with some of the granitic bodies. The heavy metal content (mainly zinc) of stream and spring waters and the cold-extractable heavy metal content of stream and spring sediments have been determined throughout the district. Most of the known sulphide bodies are indicated by higher than normal amounts of heavy metals in the water and stream sediments of nearby streams. Numerous streams with above normal contents of heavy metals in both the water and stream sediments merit further investigation. The stream and spring sediments in all stream systems of the district have been analyzed for total Pb, Zn, Cu, As, Sb, Mo, Sn, W, Ag, Ni, Co, Cr, Ba, and Mn, and the dispersion of these elements has been discussed. The background for each element varies across the district and depends essentially on the underlying bedrock. Local variations in background are evident and appear to depend on the type of bedrock, proximity to deposits or sparsely mineralized rocks, or to concentrations of strongly adsorbing gels, particularly those of hydrated manganese dioxide and ferric hydroxide. Most of the known sulphide deposits in the district are marked by higher than normal amounts of Pb, Zn, Cu, As, Sb, and Ag in the sediments of the neighbouring streams. The granitic rocks and their metamorphic aureoles give rise to higher than normal amounts of molybdenum (and tungsten in some areas) in the stream sediments draining areas underlain by and adjacent to them. In certain streams, the nickel and chromium content of the stream sediments reflects the presence of a serpentinized peridotite body. Numerous anomalies in all metals occur throughout the district. These merit further investigation. Stream sediments enriched in manganese are often likewise enriched in all of the elements determined in the survey. This results from the strong adsorptive capacity of manganese hydroxide for most metals. Due attention must be taken of this feature when assessing the significance of anomalies in all metals.
