Geologic information

Identification information

Deposit ID 10307964
Record type Site
Current site name Iron Creek (lower)

Geographic coordinates

Geographic coordinates: -165.73179, 64.72208 (WGS84)
Relative position Iron Creek is an informally named, small west tributary to Cripple River that is not shown on the current U.S. Geological Survey topographic map. This occurrence is 2 miles northeast of the Nome-Teller road. The occurrence, called the Lower Iron Creek gossan by Herreid (1970, figure 1), is about a half mile west of the mouth of Gold Run, another tributary to the Cripple River. The occurrence is at about 500 to 600 feet elevation and located to within about 500 feet.

Comments on the geologic information

  • Geologic Description = The Lower Iron Creek gossan was located by Herreid (1970, figure 1) and shown to be about 600 feet long in a north-northwest direction. It is in massive marble, probably the same as the massive marble unit of Bundtzen and others (1994). This occurrence is probably similar to other iron oxide deposts in the area such as the Cub Bear prospect (NM133) and Iron Creek prospect (NM131). Herreid (1970) noted anomalous lead at this prospect, but it is not reflected in the one sample for which an analysis was reported from the occurrence (sample 146, Herried, 1970). The origin of the iron deposits in the area is uncertain. They may be iron oxide gossan developed by the oxidation of sulfide deposits (Eakin, 1915 [B 622-I, p. 361-365]; Mulligan and Hess, 1965; Herreid, 1970). Alternatively, they could be hypogene iron oxide (and iron carbonate) deposits. Inasmuch as several similar iron deposits nearby, such as the American prospect (NM014) and the Monarch prospect (NM017), contain anomalous amounts of zinc, they could be transitional to zinc-lead-fluorite deposits such as the Quarry prospect (NM135).
  • Age = Post mid-Cretaceous, the age of metamorphism of the host carbonate rocks.
