    Etd thumbnail: Low Pressure Experiments With Basanite, Hawaiite, And Phonolite From Mt. Erebus, Antarctica.

    Description/Abstract:
    I conducted melting experiments with a basanite, two hawaiites (DVDP2 and 83415), and a phonolite from Mt. Erebus, Antarctic. All experiments were carried out a 1 atmosphere from 1224$\sp\circ$ to 1049$\sp\circ$C at oxygen fugacity near QFM buffer. I have tested two hypothesis: (1) can a basanite parent magma differentiate at low pressures to produce hawaiite and phonolite magmas, and (2) do the Mt. Erebus rocks represent low pressure differentiation of a parental basanitic magma. Microprobe analyses of glasses and coexisting crystals were used to test these hypotheses.
