Geochemical analysis of rock sample 1354 (in OFR 34-90) Rock samples were analyzed by inductively coupled plasma (ICP) spectroscopy. Samples with visible quantities of either gold, silver, platnium group elements, copper, lead, zinc, tin, molybdemum, chromium, nickel, or antimony had fire assay or atomic absorption analyses performed for those elements.

Categories: Physical Item; Tags: Geochemical Sample Geochemical analysis of rock sample 1380 (BLM) Rock samples were preconcentrated using a solution of nitric-aqua-regia leach techniques before analysis using either atomic absorption or inductively coupled argon plasma spectroscopy. Several samples were analyzed for the element using both techniques. The results from the more accurate method is reported. Several rock chip samples were analyzed for rare-earth elements (REE) by neutron activation analysis (NAA).
