ISOTOPIC RATIOS OF OXYGEN IN METEORITES AND IGNEOUS ROCKS
Journal Article

· Geochim. et Cosmochim. Acta
Data are included referring to 16 different igneous rocks and 16 different meteorites. The rocks were reduced by carbon at 1200 to 2000 C for a yield of 30 to 40 cm/sup 3/ carbon monoxide at 760 mm Hg. For quartz and granite, the reduction reaction becomes noticeable at 1300 to 1400 C; at 1200 C for dunite and olivine: and at 1000 to 1100 C for basalt, diabase, and the matter of stony meteorites. The reduction reactions for all samples were practically finished at 1900 C. The CO yield for the different objects was 95.0 to 100% with a determination accuracy of hr at 1500 deg 0.05%. (B.O.G.)
