The contents of Au, As, Sb and W in metagreywacke, slate and quartz veins from Harrigan Cove (M.A.87M/5641), were determined by NAA. The gold-bearing veins occur in the Goldenville formation, the lower sandy flysch member of the Cambrian-Lower Ordovician Meguma group of eastern Nova Scotia. The Harrigan Cove metagreywacke and slate are strongly As-enriched (arsenopyrite) and weakly enhanced in gold relative to similar barren lithologies. Greywacke is the main sink for As, while Au occurs in highest concentration in greywacke and slate, but not in the quartz veins. Anomalous gold values occur with the same frequency in greywacke, slate and quartz veins, but anomalous quartz-vein samples are much richer in Au than anomalous host-rock samples. It is suggested that the metal distributions support a polygenetic origin for the mineralization, whereby early As- and S-bearing fluids introduced arsenopyrite and sulphides, mainly into greywacke. Gold was concentrated by these minerals and later was mobilized, along with large quantities of silica, early in the deformation history, through pressure-solution processes. These silicic fluids and their metals were then injected by hydraulic fracture, mainly into slate, to form the gold-bearing, bedding-parallel quartz veins.-A.W.H.
