Abstract
Late Paleozoic sedimentary rocks in the Nelson Range consist primarily of miogeosynclinal limestones, dolomites and shales. Intrusive rocks of the Hunter Mountain batholith intruded the Keeler Canyon Formation during the Early Jurassic. Andesite porphyry dikes of the Independence dike swarm intruded both rock units during Late Jurassic through the Cretaceous. Skarn zones developed in the limestones and dolomites adjacent to the monzonite intrusive. The deformation of Paleozoic sediments by regional Mesozoic events may have occurred prior to the emplacement of the batholith. The subsequent intrusion further deformed and contorted the Paleozoic rocks. Normal faulting of Cenozoic age produced the physiographic features seen today. Mineralization occurs mostly as veins and irregular replacements along zones of fractured Paleozoic rocks near the intrusive contact. Ores primarily consist of hypogene and supergene minerals of either lead (argentiferous) or copper with minor amounts of tungsten, zinc, molybdenum and gold.
