Geologic setting

Geologic description

The rocks along Dome Creek are Paleozoic amphibolite-facies gneiss, amphibolite, quartzite, schist, marble, and greenschist (Foster, 1976). Bedrock exposed in placer cuts on benches consists of quartzite, schist, serpentinized greenstone, and marble (Mertie, 1938). The bedrock is cut by shear zones filled with greenish gouge, some of which contain granulated vein quartz with pyrite. Quaternary terrace and colluvial deposits are extensive in the vicinity.
In 1928, bench gravels were being mined about 1.5 miles downstream from the mouth of Little Miller Creek on the north bench of Dome Creek (see EA079) (Mertie, 1930 [B 813-C]). In addition to gold, placer concentrates contain minor galena and cinnabar and abundant pyrite. Bedrock in this bench cut consists of schist and marble, and the schist is cut by quartz veins that contain pyrite and arsenopyrite (Mertie, 1930 [B 813-C]). Mertie suggested that these veins may have provided a local bedrock source for placer gold.
