Glazner, A F

Work performed during the first two years of this project includes construction of furnace laboratory and calibration of instruments, installation of an electron microprobe, and determination of phase equilibria along a basalt-rhyolite mixing line. This latter study comprises the bulk of work performed to date. We completed approximately 100 experiments on the one-atmosphere phase equilibria of balalt-rhyolite mixtures. Starting materials were an alkali basalt from Pisgah Crater, California, and a high-silica rhyolite from the Bishop Tuff, Owens Valley, California. These materials were chosen because the compositional trend of the mixtures mimics many continental calc-alkaline suites. 5 figs.
