... The Jarbidge Rhyolite was originally described by Schrader (1912) , and later named, mapped, and defined as a map unit consisting of quartz-phyric lavas, flow-dome complexes, minor pyroclastic deposits, and sparse interbedded sedimentary strata by Coats (1964 , 1987) . The Jarbidge Rhyolite has been...
