GERMANIUM ISOTOPIC VARIATIONS IN IGNEOUS ROCKS AND MARINE SEDIMENTS

Rouxel O.; Galy A.; Elderfield H. (2006)

A new technique for the precise and accurate determination of Ge stable isotope compositions has been developed and applied to silicate rocks and biogenic opal. The analyses were performed using a continuous flow hydride ...
KINETIC AND EQUILIBRIUM MASS-DEPENDENT ISOTOPE FRACTIONATION LAWS IN NATURE AND THEIR GEOCHEMICAL AND COSMOCHEMICAL SIGNIFICANCE

Young E.D.; Galy A.; Nagahara H. (2002)

The mass-dependent fractionation laws that describe the partitioning of isotopes are different for kinetic and equilibrium reactions. These laws are characterized by the exponent relating the fractionation factors for two ...
MG ISOTOPE HETEROGENEITY IN THE ALLENDE METEORITE MEASURED BY UV LASER ABLATION-MC-ICPMS AND COMPARISONS WITH O ISOTOPES

Young E.D.; Ash R.D.; Galy A.; Belshaw N.S. (2002)

First results from a new UV laser ablation MC-ICPMS method for measuring Mg isotope ratios in situ in meteoritical materials show that there are mass-dependent variations in δ25Mg and δ26Mg up to 1.5 %% per amu in chondrules ...
THE ISOTOPE GEOCHEMISTRY AND COSMOCHEMISTRY OF MAGNESIUM

Young E.D.; Galy A. (2004)

Magnesium is second only to oxygen in abundance among the rock-forming elements and is an important element in the oceans and in hydrological and biological systems. Differences in the relative abundances of its three ...
