"Two hundred and fifty vein and wall rock samples were collected from Chief of the Hill and the Duplex Mines of Searchlight District, Nevada. The samples were collected along lines approximately normal to the veins. They were analyzed for lead, copper, zinc, silver, gold, arsenic, selenium, and molybdenum using neutron actication analysis and atomic absorption spectrophotometry. Gold, silver, copper, lead and zinc show well-developed anomalies in the wall rocks. In most cases, the concentration of these elements decreases gradually with increasing distance from the vein and reaches background values at a distance of 40-120 feet from the vein. Molybdenum and selenium did not show a significant difference in concentration between vein material and wall rock. The arsenic concentration was below the detection limit of the used analytical method. The available results indicate that the concentration of metal in the vein strongly influences the extent of the wall rock anomaly. The results also indicate that anomalies are better developed in the hanging wall than in the footwall of a vein"--Abstract, page ii.
