Polycyclic aromatic hydrocarbons (PAHs) in C1 and C2 Carbonaceous Chondrites appear to be the product of a high-temperature synthesis. This observation counters a prevailing view that PAHs in meteorites are a thermal alternation product of preexisting aliphatic compounds, which in turn required the presence of low-temperature mineral phases such as magnetite and hydrated phyllosilicates for their formation. Such a process would necessarily lead to a more low-temperature assemblage of PAHs, as… Expand

The great uniformity of composition and the nature of alkyl substituents suggest that most of the PAHs in the soil and in the sea-bed have been derived over eons from the fall-out of soot from forest and prairie fires, while the aromatic hydrocarbons of crude oil have been formed over millions of years from organic matter in sediments at 100 to 150 C.
