摘要：

We report here the presence of fullerenes in the iridium-rich Cretaceous-Tertiary (K-T) boundary layer in the intertrappean beds of Anjar within the Deccan Volcanic Province. Fullerenes (C-60) have been identified in or near the three iridium-rich horizons from this section by high-resolution electron-impact ionization mass spectrometry, Fourier transform infrared (FT-IR), and C-13-nuclear magnetic resonance spectroscopic techniques. Fullerenes are absent in six other iridium-poor horizons of the same section. The association of high-pressure-high-temperature forms of fullerenes with high iridium concentrations suggests that fullerenes can be used as geochemical indicators of an extraterrestrial impact.
