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: The occurrence is located about 11 miles east of the confluence of the Ribdon and Sagavanirktok Rivers at an elevation of about 2,250 ft. (NE1/4 sec. 32, T. 7 S., R. 16 E., of the Umiat Meridian). This occurrence is shown as location number 22 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: Triassic, based on the age of the host Shublik Formation (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).
