Abstract

We report an oxygen isotope analytical system for rocks and minerals using a CO2 laser-BrF5 fluorination technique that has been built at the Institute for Study of the Earth's Interior, Okayama University at Misasa, Japan. The system is basically for bulk rock d17O and d18O analysis using a few mg of silicate and oxide samples, and is applicable for oxygen 3 isotope mapping of meteorites.
