Abstract

Reconnaissance examinations for uranium were made at nine localities in the York, Nome, and Koyuk districts of the Seward Peninsula, Alaska, during .the 1951 field season. In addition carborne radiometric traverses were made of four roads in the Nome and Council districts. Only at Brooks Mountain in the York district are uranium-bearing deposits that required detailed study. On the southwest flank of Brooks Mountain, zeunerite occurs as a surface coating on quartz-tourmaline veins occupying joint fractures in granite| at a second locality, also on the southwest flank of the mountain, zeunerite is disseminated in a highly-weathered, altered zone of granite near a contact with limestone. Preliminary radiometric analyses show an average of about 0.05 percent equivalent uranium in the vein material and about 0.07 percent equivalent uranium in the weathered, altered granitic zone.
