Location: This occurrence is on a ridge at an elevation of about 1,900 feet, approximately 1.25 miles east-northeast of Eureka Dome. The site is at Alaska Division of Geological and Geophysical Surveys (ADGGS) sample station 97RN035 (Liss and others, 1998), near the south end of the west boundary of section 26, T. 5 N., R. 13 W., of the Fairbanks Meridian. The location is accurate within 500 feet.
Geology: Bedrock east of Eureka Dome, on the ridge between Minook and Eureka creeks, consists of Jurassic or Cretaceous quartzite, sandstone, and shale (Reifenstuhl and others, 1998). These rocks are in thrust-fault contact with Cretaceous or Jurassic metasedimentary rocks to the south and with Triassic or Permian sedimentary rocks to the north. A small Cretaceous monzodiorite pluton is exposed on Eureka Dome, approximately 1.5 miles to the west-southwest (Reifenstuhl and others, 1998). A sample (97RN035) of a quartz vein at the contact between quartzite and argillite on the ridge between Minook and Eureka creeks contained 360 parts per million (ppm) arsenic (Liss and others, 1998). There is no record of exploration or mining at this site.
Workings: A sample (97RN035) of a quartz vein at the contact between quartzite and argillite on the ridge between Minook and Eureka creeks contained 360 parts per million (ppm) arsenic (Liss and others, 1998). There is no record of exploration or mining at this site.
