Abstract

By means of high-resolution transmission electron microscopy, both C 60 and C70 fullerenes have been found in a carbon-rich Precambrian rock from Russia. The fullerenes were confirmed by Fourier transform mass spectrometry with both laser desorption and thermal desorption/electron- capture methods to verify that the fullerenes were indeed present in the geological sample and were not generated by the laser ionization event. The mass spectra were measured under conditions sufficient to resolve the 13C/12C isotopic ratios for C60 and C 70 and indicate that these ratios correspond to the normal range of isotopic values.
