IRON METEORITES HAVE BEEN FOUND TO BE REMNANTS OF THE EARLIEST FORMED PLANETESIMALS IN THE SOLAR SYSTEM BY HF-W CHRONOLOGY. HOWEVER, THEIR INITIAL W ISOTOPE COMPOSITION IS SKEWED TO APPARENTLY EARLY AGES BY NEUTRON CAPTURE DURING COSMIC RAY IRRADIATION C

THE HIGHEST PRIORITY AMONG THE ORIGINAL SCIENCE OBJECTIVES OF THE GENESIS MISSION IS MEASUREMENT OF THE SOLAR WIND OXYGEN ISOTOPIC COMPOSITION WHICH HAS BEEN PARTIALLY MET WITH PRECISE OXYGEN ISOTOPE DATA ON THE CONCENTRATOR TARGET. THE MEASURED OXYGEN IS
