Location and accuracy | Located on hill just east of Nanielik Creek in T. 29 N., R. 1 W., Kateel River Meridian. Shown as locality 1 in Mayfield and Grybeck (1978) and accurate to within 2000 ft. (600 m). |
Geologic descriptionThree foot (1 m) thick vein of barite in limestone. Vein and nearby Fe-rich soil contained 1000 ppm Pb and 5000 ppm Zn (Mayfield and Grybeck, 1978). Occurrence could be similar to several other sediment-hosted occurrences in the Brooks Range that formed from the dewatering of a large Paleozoic? sedimentary basin (Schmidt, 1997, p. 35-65; Schmidt and Werdon, 1993, p. 143). | |
