Comments on the geologic information

  • Geologic Description = 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).
  • Ore Material = Phosphate rock
  • Age = Triassic, based on the age of the host Shublik Formation (as mapped by Menzie and others, 1985).

General comments

Subject category Comment text
Deposit Model Name = Upwelling-type phosphate deposits (Cox and Singer, 1986; model 34c).
Deposit Other Comments = 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).
