The fractionation of oxygen isotopes between apatite and calcite has been measured experimentally using the direct exchange technique in a piston-cylinder apparatus at high temperature and pressure (350-800°C, 1.1 GPa). ...
A Cameca 4f ion microprobe has been used in conjunction with laser and conventional analytical techniques to measure the oxygen isotope fractionation between magnetite and water at 350°C. A set of experiments in which large ...
