Organic geochemistry of some Georgia–South Carolina clays: C19—C28 isoprenoids and the possible presence of a sesterterpene-derived hydrocarbon
Abstract
The lipid extracts from several samples of Georgia–S. Carolina kaolins contained in abundance the regular C19–C28 isoprenoid alkanes as well as a tetracyclic compound C24H42 which seems likely to have been derived diagenetically from sesterterpenes of hydrochrysene structure.
