|Location and accuracy||This occurrence is on the south ridge of Vermont Dome, about 0.5 mile south of the summit. Mulligan (1974) described the location as near the crest of the spur that extends southward from the summit of the Dome. The occurrence is at an elevation of about 3,550 feet on this spur. The location is accurate within one-half mile.|
Geologic descriptionBrosge and Reiser (1960) describe this occurrence as unidentified copper sulfides and malachite stains in Devonian phyllite and siltstone. Mulligan (1974) noted green-stained, light-brown float of quartz vein material with traces of copper, zinc, and iron sulfides, and tiny pods of goethite, along fracture planes in schist fragments found in talus. Eden (2000) collected samples, mostly float, of locally iron-stained quartz on the south side of Vermont Dome. One sample was weakly anomalous in Cu and another weakly anomalous in Pb. His mapping identifies the rocks in the area as Upper Devonian, gray-black phyllite and pelitic mica schist of the Beaucoup Formation. Kurtak and others (2002) report gem-quality quartz near this site.
