|Location and accuracy||This locality is on a ridgecrest at 2,500 feet elevation between the headwater forks of Henry Creek, a west tributary to the Kougarok River. It is 4.5 miles southeast of the summit of Kougarok Mountain in the east-central Teller C-1 quadrangle. This is locality 17 of Cobb and Sainsbury (1972) who called it the Worcester prospect. However, the lack of observed mineralization here (Sainsbury, and others, 1969, p. 22) suggests that the Worcester prospect (TE075) is another locality one mile to the south (locality 18 of Cobb and Sainsbury, 1972). Cobb (1975) summarized references to this locality under the name 'Unnamed occurrence'.|
Geologic descriptionThis is a large area of silica-rich rock within a marble assemblage. Mineralization was not observed in these rocks (Sainsbury and others, 1969, p. 22) although it was recorded as a separate locality by Cobb and Sainsbury (1972). The silica-rich rocks are 'contorted' and may be quartzite.
|Geologic map unit||(-165.140690864979, 65.628269665665)|
|Mineral deposit model||Silica-rich zone, possibly quartzite, within a marble assemblage. This occurrence is not a strong analog to defined deposit models.|
|Age of mineralization||Paleozoic (?); the silica-rich rocks are apparently metamorphosed and would therefore predate mid-Mesozoic deformation and metamorphism in the region. The associated marbles are probably Paleozoic in age.|
|Workings or exploration||None|
|Indication of production||None|
