Copper transport by high temperature, sulfur-rich magmatic vapor: Evidence from silicate melt and vapor inclusions in a basaltic andesite from the Villarrica volcano (Chile)

Autor: Zoltán Zajacz, Werner E. Halter

Publikováno v: Earth and Planetary Science Letters. 282:115-121

Silicate melt inclusions have been analyzed in co-crystallized plagioclase, olivine and clinopyroxene in a typical arc-related basaltic-andesite from the Villarrica volcano (Chile). The melt inclusions show identical compositions with respect to most

29Si NMR spectroscopy of silica glass: T1 relaxation and constraints on the Si–O–Si bond angle distribution

Autor: Wim J. Malfait, Werner E. Halter, René Verel

Publikováno v: Chemical Geology. 256:269-277

A 29 Si NMR spectrum with high signal to noise ratio was collected from a well-characterized, isotopically-enriched SiO 2 glass with a single scan after full relaxation of the magnetization. From the spectrum, the average Si–O–Si bond angle was e

Increased 29Si NMR sensitivity in glasses with a Carr–Purcell–Meiboom–Gill echotrain

Autor: Wim J. Malfait, Werner E. Halter

Publikováno v: Journal of Non-Crystalline Solids. 354:4107-4114

The use of a Carr–Purcell–Meiboom–Gill (CPMG) echotrain to increase the 29 Si NMR sensitivity in glasses was investigated. The echo intensity decay follows a stretched exponential behavior M( t ) = M 0 exp[−( t / t 2) β ] with values for the

Determination of fluid/melt partition coefficients by LA-ICPMS analysis of co-existing fluid and silicate melt inclusions: Controls on element partitioning

Autor: Marcel Guillong, Zoltán Zajacz, Thomas Pettke, Werner E. Halter

Publikováno v: Geochimica et Cosmochimica Acta. 72:2169-2197

Analyses of co-existing silicate melt and fluid inclusions, entrapped in quartz crystals in volatile saturated magmatic systems, allowed direct quantitative determination of fluid/melt partition coefficients. Investigations of various granitic system
