|Location and accuracy||Prospect located on the easternmost distributary of Kijik River, near where the river enters Lake Clark. Locality 22 of Nelson and others (1985) and locality 13 of MacKevett and Holloway (1977). Locality accurate within 1,600 m.|
Geologic descriptionPlacer claims along Kijik River near Lake Clark. Rock units in the Kijik River drainage include: rhyolitic breccia, ash-flow tuff, flows, and intrusive rocks and subordinate mafic to intermediate flows (Nelson and others, 1983; unit Tv). And Unit TKi10, a granite porphyry with phenocrysts of quartz, plagioclase, and potassic feldspar up to 4 mm across in a groundmass of quartz, potassic feldspar, and plagioclase grains up to 1 mm across. Potassium-argon ages for unit Tv range from 56.2 to 62.7 m.y. indicating a Tertiary age for these rocks (Eakins and others, 1978).
