Notes

Over 30 disseminated gold or hot-spring deposits in the western U.S. were sampled for ammonium-bearing minerals during field reconnaissance studies (Figs. l and 2). Wholerock samples, approximately 3 cm across, were collected from primarily feldspathic or argillaceous lithologies and measured on a laboratory near-infrared spectrometer (Krohn and Altaner, 1987).
