Microprobe analysis of biotites - A method of correlating tuff beds in the Green River Formation, Colorado and Utah Microprobe analysis of biotites - A method of correlating tuff beds in the Green River Formation, Colorado and Utah
Quantitative electron microprobe analyses of biotite grains for iron, magnesium, and titanium from tuff beds in the lacustrine Green River Formation (Eocene) of Colorado and Utah provide a tentative method of identification and a permissive stratigraphic correlation of tuffs. Tuff beds that have been identified and correlated by stratigraphic means were sampled at five localities in...
