Comments on the geologic information

  • Geologic Description = Phosphatic rock is present in the lower 6 meters (20 ft) of a 30 meter (100 ft) -thick succession of black oolitic limestone in the basal part of the Schublik Fm. The phosphate rock is fine-grained and contains uniform dimentional oblong phosphatic pellets that average 0.2 long and 0.1 millimeters across. Angular grains of quartz make up 3% of rock. One sample contained 35.8 per cent P2O5 and 0.008% U and has the highest phosphate content of any sample collected from the Shublik Formation.
  • Age = Triassic
