|Location and accuracy||This occurrence is on the ridge crest at the head of Arctic Creek, 3.8 miles southeast of Taylor on the Nome-Taylor road. Sainsbury and others (1969) report mineralization in marble outcrops just to the east of the road here. This is locality 3 of Cobb (1972; MF 417; 1975; OFR 75-429).|
Geologic descriptionMarble interlayered in pelitic schist forms outcrops just east of the Nome-Taylor road. Sainsbury and others (1969) describe replacements of marble by banded, fine-grained silica containing pyrite and traces of chalcopyrite. Although mapped as klippe by Sainsbury and others (1969), the marble is interlayered with schist and part of a low grade, Lower Paleozoic metasedimentary assemblage (Till and others, 1986).
|Geologic map unit||(-164.690692406715, 65.6452756111208)|
|Mineral deposit model||Siliceous zones in marble with pyrite and traces of chalcopyrite|
|Age of mineralization||Unknown but possibly Cretaceous; the major episode of epigenetic mineralization on Seward Peninsula accompanied higher temperature metamophism and mid- to Late Cretaceous granitic plutonism in the region.|
|Alteration of deposit||Silica replacements of marble?|
|Workings or exploration||Some shallow prospecting pits may be present.|
|Indication of production||None|
