These aromatic biomarkers are unfortunately rarely used in petroleum geochemistry. They have the five-ring structure of the hopanes but with an aromatic ring fused to the E-ring in place of the normal side chain.

Although an unfamiliar molecule to many petroleum geochemists, bacteriohopanetetrol (BHT) is nevertheless an important one, being a major source of the hopanes found in oils and their source rocks (Ourisson et al. , 1984).

Oleanane is present in only some oils and source rocks. It occurs as two isomers – 18α(H) and 18b(H) – and is typically found as a doublet peak in the m/z 191 mass chromatogram eluting just before the C30 αb hopane.

The C29 hopane, 30-norhopane, is not only a member of the series of regular hopanes but also of a less common series that lack the methyl group at C-22 in the side chain, the 30-norhopanes.

In petroleum geochemistry, a source rock is classified as an interval of rock that contains sufficient organic matter of the right type that has the potential to generate, or has already generated, commercial quantities of hydrocarbons.
