A new method for measuring the relative abundances of oxygen isotopes in silicate rocks is described. The silicate is reacted with carbon at about 2000° in a high vacuum resistance furnace and the CO thus produced is collected and fed into a double collector mass spectrometer. By taking the necessary precautionary measures it is possible to determin the 18 O/ 16 O ratios with a relative accuracy of about 0,6°/ 00 .
