Geologic information

Identification information

Deposit ID 10308429
Record type Site
Current site name Kreuger Creek

Geographic coordinates

Geographic coordinates: -166.09745, 65.9293 (WGS84)
Relative position Kreuger Creek is a south-flowing tributary to the Arctic River that drains the east side of Ear Mountain. Ear Mountain is an isolated upland reaching 2,329 feet elevation in the north-central Teller D-3 quadrangle. Kreuger Creek has west tributaries, including Eldorado Creek (TE068), that extend across the contact zone and into east and north parts of the Ear Mountain granite stock. Eldorado Creek actually heads in an area of significant lode tin and related metallization at North Hill (Ear Mountain prospect, TE060). This is locality 64 of Cobb and Sainsbury (1972). Cobb (1975) summarized relevant references under the name 'Kreuger Cr.'.

Comments on the geologic information

  • Geologic Description = The segment of Kreuger Creek referred to here is the 0.5 miles at and below the confluence with Eldorado Creek. Eldorado Creek has headwaters that cross the northeast contact zone of the Ear Mountain granite stock (Sainsbury, 1972). This stock is a Late Cretaceous (76.7 +/- 2.9 my; Hudson and Arth, 1983, p. 769) composite biotite granite that intrudes an impure and schistose carbonate sequence, with some metapelitic rocks, of unknown but probable Paleozoic age. The country rocks are variably converted to tactite and hornfels around the granite stock (Knopf, 1908, p. 28-29). Churn-drill holes on this part of Kreuger Creek contain a trace to 0.71 pounds of tin per cubic yard from a pay horizon that varies from 5 to 16 feet thick. Total gravel thickness varies from 6 to 22.5 feet thick. Heavy mineral identifications are not available but the mineralogy here is probably similar to that from the headwaters of Eldorado Creek (TE068).
