Geographic coordinates

Geographic coordinates: -171.65323, 63.75913 (WGS84)
Relative position Tiflighak Bay is a small concave shoreline on the east side of the northwest tip of St.Lawrence Island. This is an area of steep sea cliffs cut into intrusive rocks of the Sevuokuk pluton. This location is only known from an oral communication (Cobb, 1980, p. 60). Small galena-bearing quartz veins are said to be exposed near the top of the cliff. This site is probably located within 0.5 mile. It is locality 1 of Cobb (1972) and Cobb (1980) summarized relevant references under the name 'Tiflighak Bay'.

Comments on the geologic information

  • Geologic Description = Galena in small quartz veins in Cretaceous quartz monzonite exposed near top of cliff (oral communication, Bela Csejtey, Jr. May 24, 1972; as cited by Cobb, 1972; 1980).??The Sevuokuk pluton in the vicinity of this site is biotite quartz monzonite (Csejtey, Patton and Miller, 1971) for which one K/Ar determination indicates an age of 108 +/- 3.2 Ma (Patton and Csejtey, 1980).
  • Age = Not known; assumed to be mid -Cretaceous, the age of the associated granitic rocks.
