Figure 2
Bedrock geology of the Rouyn-Noranda study area24. The northern and central parts of the study area are dominated by Archean volcanic units of the Blake River Group, which is a southern unit of the Superior Province’s Abitibi greenstone belt. The southern part of the Rouyn-Noranda study area is partly comprised of predominantly sedimentary units of the Timiskaming Group, the Cadillac Group, the Cobalt Group, and the Pontiac Group. The location of the Horne smelter is given by a black circle at lower center, immediately west of Lac Osisko. The locations of sites depicted in Figs 4 and 5 are identified by white circles and are labeled by figure number. Sites depicted in Fig. 3A,B are located in the same general area as given for Fig. 4H.
