Exploration Activity: Rock Sampling At U.S. West Region (Krohn, Et Al., 1993)
|Exploration Activity Details|
|Location||U.S. West Region|
|Exploration Technique||Rock Sampling|
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).
