Fullerenes from the Geological Environment
@article{Buseck1992FullerenesFT, title={Fullerenes from the Geological Environment}, author={Peter R. Buseck and Semeon J. Tsipursky and Robert L. Hettich}, journal={Science}, year={1992}, volume={257}, pages={215 - 217} }
By means of high-resoluton transmission electron microscopy, both C60 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…

The oxidation of the fullerenes during the 1.85 billion years of exposure was apparently prevented by the presence of sulfur in the form of sulfide-silicate complexes associated with the fulrerenes.

High-pressure liquid chromatography with ultraviolet-visible spectral analysis of toluene extracts of samples from two Cretaceous-Tertiary boundary sites in New Zealand has revealed the presence of C60, which may have originated in the extensive wildfires that were associated with the cataclysmic impact event that terminated the Mezozoic era.
