[2014-01-10] The effect of prograde metamorphism on the chlorine isotope compositions of sedimentary rocks Chlorine stable isotope compositions of two Swiss sedimentary sequences and their metamorphic equivalents were measured in order to study fractionation effects during prograde metamorphism and devolatilization. Protoliths ...
[2006-08-30] Oxygen isotope evidence for subduction and rift-related mantle metasomatism beneath the Colorado Plateau-Rio Grande rift transition Spinel lherzolite and pyroxenite xenoliths from the Rio Puerco Volcanic Field, New Mexico, were analyzed for oxygen isotope ratios by laser fluorination. In lherzolites, olivine d18O values are high (+5.5 per mil), whereas ...
[2007-10-29] Relationships between fluid composition and rheology in ecologites from the eastern Alps Finely banded, dolomite-rich mafic eclogites from the Tauern Window equilibrated at >2 GPa/600-650°C. Previous work (Selverstone et al. 1992; Getty & Selverstone, 1994) showed that: a(H2O) varied from ~0.2 to 0.9 across ...
[2014-07-21] Water vapor isotopic composition of a stratospheric air intrusion: Measurements from the Chajnantor Plateau, Chile This dataset contains ozone and water vapor isotopic measurements for August, 2012, from the Chajnantor Plateau.
