Comments on the geologic information

  • Geologic Description = Limonitic rocks occur in a synform near the base of a marble unit (Herreid, 1970, figure 1). According to Mulligan and Hess (1965), samples of outcrop consist of finely crystalline marble with minor disseminated limonite and limonitic cavity fillings; sericitic schist with minor earthy and compacted limonite and accessory rutile is also present. Associated schist consists of chlorite, limonite, quartz, biotite, sericite, manganese oxides (pyrolusite?), and minor clay. There is an estimated resource of 12,000 long tons of material that contains 20 to 40 percent iron and 20,000 long tons of 10 to 20 percent iron (Shallit, 1942; Mulligan and Hess, 1965, table 3). Mulligan and Hess (1965) found no evidence of sulfides at this deposit, and samples collected by Herreid (1970) contained only as much as 220 ppm zinc.
  • Age = Post mid-Cretaceous, the age of metamorphism of the host schist and marble.
  • Age = Host rock is Pre Campanian - Post Barremian.
