    Description / Table of Contents: Volatile components, by which we mean those magma constituents which typically prefer to occur in the gaseous or super-critical fluid state, may influence virtually every aspect of igneous petrology. The study of volatile-bearing systems, both in nature and in the laboratory, has far exceeded the relative abundances of these components in igneous rocks, yet in many ways the words of Bowen (1928) are still broadly applicable: " ... to many petrologists a volatile component is exactly like a Maxwell demon; it does just what one may wish it to do." (Bowen, 1928, p. 282) What we hope to show in this volume are some areas of progress in understanding the behavior of magmatic volatiles and their influence on a wide variety of geological phenomena; in doing this it also becomes apparent that there remain many questions outstanding. The range of topics we have tried to cover is broad, going from atomisticscale aspects of volatile solubility mechanisms and attendant effects on melt physical properties, to the chemistry of volcanic gases and the concentrations of volatiles in magmas, to the global geochemical cycles of volatiles. The reader should quickly see that much progress has been made since Bowen voiced his concerns about Maxwell demons, but like much scientific progress, answers to old questions have prompted even greater numbers of new questions. The Voltiles in Magmas course was organized and transpired at the Napa Valley Sheraton Hotel in California, December 2-4, 1994, just prior to the Fall Meetings of the American Geophysical Union in San Francisco.

    Notes: Abstract Anhydrous partial melting experiments, at 10 to 30 kbar from solidus to near liquidus temperature, have been performed on an iron-rich martian mantle composition, DW. The DW subsolidus assemblage from ≤5 kbar to at least 24 kbar is a spinel lherzolite. At 25 kbar garnet is stable at the solidus along with spinel. The clinopyroxene stable on the DW solidus at and above 10 kbar is a pigeonitic clinopyroxene. Pigeonitic clinopyroxene is the first phase to melt out of the spinel lherzolite assemblage at less than 20°C above the solidus. Spinel melts out of the assemblage about 50°C above the solidus followed by a 150° to 200°C temperature interval where melts are in equilibrium with orthopyroxene and olivine. The temperature interval over which pigeonitic clinopyroxene melts out of an iron-rich spinel lherzolite assemblage is smaller than the temperature interval over which augite melts out of an iron-poor spinel lherzolite assemblage. The dominant solidus assemblage in the source regions of the Tharsis plateau, and for a large percentage of the martian mantle, is a spinel lherzolite.

    Notes: [Auszug] SIR - Ever since C60 was discovered1, there has been anticipation of the possible use of the fluorinated derivatives, and C60F60 in particular, as lubricants. There are indications, however, that, unlike Teflon, this material might not be chemically stable: fluorination of C60 is ...

    Notes: Abstract The solubility of carbon dioxide in a Ca-rich leucitite has been investigated as a function of pressure (0.1–2.0 GPa), temperature (1200–1600°C), and oxygen fugacity. The experiments were done in a rapid-quench internally-heated pressure vessel (0.1 GPa) and a piston cylinder (0.5–2.0 GPa). The leucitite glass, previously equilibrated at NNO, and silver oxalate were loaded in Fe-doped Pt capsules (oxidized conditions) and graphitelined Pt capsules (reduced conditions). Secondary Ion Mass Spectrometry and bulk carbon analyses were used to determine the amount of dissolved carbon. Speciation of carbon was characterized by Fourier transform microinfrared spectroscopy. At oxidized conditions, only CO3 2- is observed as a dissolved species. The solubility is high with CO2 contents in the melt attaining 6.2 wt% at 2.0 GPa and 1350°C. The solubility increases with pressure and shows a significant negative temperature dependence. An excellent correlation is obtained when the data are fit to a model, based on the simplified solubility reaction CO2 (vapor)+O2-(melt)⇒CO3 2-(melt), which describes the solubility of CO2 as a function of pressure, temperature and fCO2. At reduced conditions, the amount of carbon dissolved is significantly lower, and CO3 2- is still the only species present in the melt. If the solubility model established at oxidized conditions is applied, the carbon dissolved appears to be essentially a function of fCO2 alone although divergence increases in a consistent manner with pressure and temperature. This could suggest a low but significant solubility of CO with a positive temperature dependence or a departure of the calculated fluid compositions determined by the equation of state from the actual ones. The strong preferential solubility of carbon in its oxidized C4+ form, even at reduced conditions, implies that ascending melts with high CO2 solubility can experience significant oxidation through degassing. This could reconcile the oxidized nature of some Ca-rich alkaline magmas with more reduced mantle source regions.

    Notes: Abstract Primary melt and coexisting mineral compositions, at increasing degrees of partial melting at 15 kbar, were determined for an iron-rich martian mantle composition, DW. The composition of primary melts near the solidus was determined with basalt-peridotite sandwich experiments. In order to evaluate the approach of the liquids to equilibrium with a DW mantle assemblage, experiments were also performed to establish the liquidus mineralogy of the primary melts. Primary melt compositions produced from an iron-rich mantle are more picritic than those produced from an iron-poor mantle. By increasing the iron content of a model mantle composition (decreasing the mg#, where mg# = atomic [Mg/(Mg+Fe2+)*100]), picritic and komatiitic magmas result at lower percentages of melting and at temperatures closer to the solidus than in an iron-poor mantle. Terrestrial iron-rich primitive volcanics may be the partial melting products of iron-rich, mg# ≥80, source regions. The DW partial melting results support the conclusion of previous authors that the parent magmas of the SNC (shergottites, nakhlites, chassignites) meteorites were derived from a source region that had been previously depleted in an aluminous phase.
