From abstract: Results of a reconnaissance geochemical survey of the Iron Mountain Quadrangle, Michigan; Wisconsin are reported. Field and laboratory data are presented for 479 groundwater samples, 369 stream sediment samples, and 389 stream water samples. Statistical and areal distributions of uranium and other possible uranium-related variables are displayed. A generalized geologic map of the survey area is provided, and pertinent geologic factors which may be of significance in evaluating the potential for uranium mineralization are briefly discussed.
