James M. Barker, Virginia T. McLemore, Marc L. Wilson, and George S. Austin


East Grants Ridge is relativety small, yet contains a variety of important mineral deposits. It lies only a few km northeast or Grants, New Mexico, and is composed of Mesozoic through Tertiary sedimentary and volcanic rocks. These rocks contain deposits of pumice, uranium and perlite that are being mined or were mined in the recent past. Scoria, limestone, topaz, garnet and obsidian also occur. These rocks and minerals interest the geologist as well as the collector, nor only as specimens, hut as indicators of other possibly economic mineral deposits,
