Distribution of gold, silver, copper, lead and zinc in the productive Marysville stock, Montana
125 whole rock samples from the productive Marysville, Montana, granodiorite and the surrounding metamorphic rocks were analyzed by neutron activation analysis for gold and silver, and by atomic absorption for copper, lead and zinc. In the vicinity of known gold veins, anomalous values for gold and silver were found in both types of bedrock. Anomalies for the base metals were much less pronounced. The results indicate that systematic analysis of igneous bodies could be useful in exploration for hydrothermal ore deposits.
