Geologic information

Identification information

Deposit ID 10307449
Record type Site
Current site name Stepovich

Geographic coordinates

Geographic coordinates: -147.32994, 64.97868 (WGS84)
Relative position The accuracy of this location is uncertain and is based on a location reported by Cobb (1976 [OFR 76-662, p. 145]), which was in turn based on a sketch map by Chapin (1914 [B 592-J, p. 330]). The coordinates locate the Stepovich prospect on the ridge west of Pearl Creek, south of Yellow Pup mine (FB118) about one mile east-southeast of Gilmore Dome in the NW1/4 sec. 27, T. 2 N., R. 2 E., Fairbanks Meridian. (Note that there another Stepovich deposit nearby, a tungsten mine (FB113).)

Comments on the geologic information

  • Geologic Description = A 38-foot shaft was sunk on a quartz vein that strikes N. 70 E. and dips 70 NW. Quartz on the dump contains bunches of arsenopyrite and a little pyrite; fractures are cemented by scorodite (Chapin, 1914 [B 592-J, p. 330]). The bedrock is quartz-muscovite schist, quartzite, and chlorite-quartz schist of the Fairbanks Schist (Newberry and others, 1996). On the ridge, just above this prospect the bedrock is amphibolite, magnetite-rich biotite schist, quartz schist, and marble. The prospect is bordered on the south and east by Cretaceous granite and granodiorite.
