Peaks at 720 and 840 atomic mass units were identified by mass spectrometry in a sample extracted from a fulgurite, which is a glassy rock that forms where lightning strikes the ground. The peaks are interpreted as arising from C60 and C70 and the associated peaks as produced from other fullerenes. The intense conditions generated by the lightning not only melted the rock it struck and fused the associated soil but also allowed fullerenes to form, presumably from the organic debris in the soil. 

Geological fullerenes: review and analysis

The search for fullerenes in rocks from the Ries impact crater

Abstract— Since their discovery, fullerenes have been reported from various geological environments. One group of these findings has been related to bolide impacts, e.g., the Sudbury crater and the

Search for Fullerenes in Geological Carbonaceous Samples Altered by Experimental Lightning

Abstract Three rocks with different organic carbon content, graptolitic shale, metamorphosed black schist and bituminous coal, have been subjected to high‐energy electric impulses of current

Origins of fullerenes in rocks.

This article is a technical comment and author response to the the discovery of naturally occuring fullerenes in Shunga rock samples, providing a rebuttal with further comments including parallels to other minerological occurences.

Fullerenes in the Cretaceous-Tertiary Boundary

Fullerenes C60 and C70 were found in the thin clay seams of nine worldwide locations of the geologic boundary between the Cretaceous and Tertiary periods. These clays are also rich in soot. One

A Raman spectroscopic study of a fulgurite

The Raman spectra revealed several forms of crystalline and fused silica and also the presence of polyaromatic hydrocarbons found in an interfacial zone of a glass bubble, suggesting that some regions of the fulgurite specimen were not subjected to temperatures of 1800°C, which are attained when lightning hits the surface of sand or a rock.

Fullerenes in the Cretaceous-Tertiary Boundary Layer

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.

Fullerenes: an extraterrestrial carbon carrier phase for noble gases.

It is determined that both the Allende and Murchison fullerene cage structure and the KTB fullerenes contain trapped noble gases with ratios that can only be described as extraterrestrial in origin.

By means of high-resoluton transmission electron microscopy, both C60 and C70 fullerenes have been found in a, carbon-rich Precambrian rock from Russia and indicate that these ratios correspond to the normal range of isotopic values.

Spectroscopic studies reveal the presence of C60 and C70 in yields and ratios that depend on temperature, pressure, carbon/oxygen ratio and residence time in the flame, and control of these conditions allows optimal yields.
