“…It also contains Cretaceous or Eocene Zn-Pb-Ag ± Au ± Ba replacement and vein deposits (Hall, 1985;Hobbs, 1985;Burton and Link, 1995;Mahoney, 1995;Turner and Otto, 1995;Winkler et al, 1995), and some of the associated host structures and fl uid pathways are inferred to have originated during Late Devonian-Early Mississippian Antler-age deformation (Turner andOtto, 1988, 1995). In east-central Idaho, a parallel, northweststriking belt of Devonian-Mississippian continental shelf carbonate rocks hosts Zn-Pb-Ag mineralization in MVT deposits that may be Cretaceous or Eocene (Skipp et al, 1983;Hobbs, 1985) as well as in similar age replacement and vein deposits (Albers, 1983;Skipp et al, 1983;Hobbs, 1985;Ruppel and Lopez, 1988).…”
