Pb and Sr isotope data have been collected from fluid inclusions trapped in syntectonic quartz veins associated with the Gavarnie thrust in the central Pyrenees, and from lithologies in the footwall and hanging wall of the thrust. These data suggest

Early Cretaceous (146–115 Ma) magmatism in the region of Mt. Hermon, Northern Israel, is part of an extensive Mesozoic igneous province within the Levant associated with the evolution of the Neotethyan passive margin of Gondwana. The initial stages

Chlorine stable isotope ratios, Cl-37/Cl-35, currently are measured using dual-inlet and thermal-ionization mass spectrometry, These two different analytical techniques, however, have never been cross calibrated. A set of samples with chlorine stable

Data from published oxygen isotope exchange experiments involving H2O and CO2 have been used to determine the reduced partition function ratios of liquid and supercritical fluid H2O and CO2. These data are compared with a recalculation of the reduced

Pb isotope compositions of acid-leached clinopyroxene and amphibole mineral separates from spinel peridotite mantle xenoliths entrained in Tertiary-Quaternary alkali basalts from the Carpathian-Pannonian Region of eastern Europe provide important con

A total dissolution technique has been developed and used to identify and quantify the incompatible element contents of fluids trapped in inclusions in minerals from peridotite xenoliths using “fluids” in the generic sense (i.e., COH fluids

The equilibrium oxygen isotope fractionation between grossular/andradite garnet and calcite has been determined experimentally by direct exchange from 800–1200°C at ∼23 kbar. A least-squares fit to the equilibrium fractionation data reflected th

Silica-poor, calcium-rich melilitites form a chemical and isotopic end-member of the spectrum of mafic magmas of the Tertiary-Quaternary volcanic province of western and central Europe. We propose that these unusual magmas are derived by partial melt

The effects of packing materials on H infiltration into sample capsules during pistoncylinder experiments has been examined using samples of oxalic acid dihydrate, silver oxalate, and pure carbon dioxide. Mass scans revealed that as much as several m

Equilibrium stable isotope fractionation factors between carbon dioxide and calcite were determined by direct equilibration of the two phases at 900°C and 12.5 kbar. The results of six three-day runs gave Δ13C(CO2-calcite) and Δ18O(CO2-calcite) fr
