| Comment | Sample of moderately welded, hornblende-bearing, crystal-rich tuff from the youngest of a sequence of rhyolitic ash-flow tuffs correlative with the Blue Sphinx Tuff in the Gillis and Gabbs Valley Ranges Ekren and others, in press at time. Dated biotite is oxidized and is 2 to 3 million years too young on the basis of position of tuff beneath the Poinsettia Tuff Member of the Hu-Pwi Rhyodacite, which has been dated at 22.1 +/- 0.7 plag, 23.1 +/- 0.7 bio from the Gabbs Valley Range to the east Ekren and others, in press at time; Morton and others, 1977; #23, p.23. |
