Magnesium (Mg) has an atomic number of 12 and belongs to the alkaline earth element
(Group II) of the Periodic Table. The pure Mg is a silvery white metal and has a melting point …

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 …

This chapter is devoted to the analytical methods employed for making high precision
isotope ratio measurements that preserve naturally occurring mass-dependent isotopic …

To investigate whether magnesium isotopes are fractionated during basalt differentiation, we
have performed high-precision Mg isotopic analyses by multi-collector inductively coupled …

We present whole rock Li and Mg isotope analyses of 33 ultramafic xenoliths from the
terrestrial mantle, which we compare with analyses of 30 (mostly chondritic) meteorites. The …

Highly precise and accurate ion microprobe analyses of oxygen three-isotope ratios in
chondrules from the Acfer 094, one of the most primitive carbonaceous chondrites, show that …

ε65Cu ([65Cu/63Cusample/65Cu/63CuNIST-976− 1]* 10,000) in chalcopyrite from the 3
three igneous intrusions that make up the Grasberg Igneous Complex (GIC) and associated …

A quantitative understanding of the elemental and isotopic fractionations recorded in the
compositions of the chondritic meteorites would provide fundamental constraints for …

We have measured the Li isotope ratios of a range of co-existing phases from peridotites
and mafic magmas to investigate high-temperature fractionations of 7Li/6Li. The Li isotopic …

This study presents major-, trace-element and Mg isotope data for the dissolved load and
suspended particulates of Icelandic rivers draining dominantly basaltic catchments …
