Comments on the geologic information

  • Geologic Description = Fluorite occurrences in the Philip Smith Mountains quadrangle have not been described individually. In general, fluorite found throughout the northern portion of the quadrangle has been described as 'microscopic interstitial and replacement crystals or as megascopic crystals and veins in the upper few hundred meters of the Lisburne Group and the basal beds of the Sadlerochit Group' (Menzie and others, 1985). The origin of the fluorite is uncertain. It may either be sedimentary (apparent stratabound distribution) or hydrothermal (local igneous associations) (Menzie and others, 1985).

General comments

Subject category Comment text
Deposit Other Comments = Fluorite is reported to occur at widespread localities across the entire northern part of the Philip Smith mountains quadrangle. These occurrences extend to the east into the Arctic quadrangle, where thick veins and isolated crystals associated with Paleozoic volcanic rocks at the top of the Lisburne Group are reported.
