Köppen climate type:
The Philip Smith Mountains quadrangle contains rock types permissive for the occurrence of phosphate deposits. Phosphate rock is locally abundant in the Mississippian Lisburne Group to the west of the quadrangle but was not noted in that formation within this quadrangle. Samples of phosphate rock from the quadrangle were not analyzed for uranium; however, there are reports of uranium in samples of phosphate rock in adjacent quadrangles (Menzie and others, 1985).
Location: Site is approximately 6.5 miles southwest of Toolik Lake (NW1/4 sec. 16, T. 10 S., R. 10 E., of the Umiat Meridian) at an elevation of about 2,550 ft. This occurrence is shown as location No. 11 in Menzie and others (1985). Location accurate within 1-mile radius.
Geology: Phosphate occurrences in the quadrangle have not been described individually but in general occur most commonly as thin, low-grade concentrations, which are estimated to probably average less than one percent of the host rock matrix (Menzie and others, 1985). The permissive rocks for the phosphate occurrences in the quadrangle are the black, calcareous phosphatic siltstones and shales of the Triassic Shublik Formation. Minor amounts of phosphate rock also occur within the Kongakut and Okpikruak Formations, Kingak Shale, and Sadlerochit Group (Menzie and others, 1985).
Age: Jurassic to Early Cretaceous, based on the age of the host Early Cretaceous Fortress Mountain, Okpikruak, and Kongakut Formations and Jurassic Kingak Shale (as mapped by Menzie and others, 1985).
Commodities (Major) - P2O5
Development Status: None
Deposit Model: Upwelling-type phosphate deposits (Cox and Singer, 1986; model 34c).
