Experiments to demonstrate the high-pressure genesis of petroleum hydrocarbons have been carried out using only 99.9% pure solid iron oxide, FeO, and marble, CaCO3, wet with triple-distilled water. There were no biotic compounds or hydrocarbons admitted to the reaction chamber. The use of marble instead of elemental carbon was intentionally conservative. The initial carbon compound, CaCO3, is more oxidized and of lower chemical potential, all of which rendered the system more resistant to the reduction of carbon to form heavy alkanes than it would be under conditions of the mantle of the Earth. Although there has been observed igneous CaCO3 (carbonatite) of mantle origin, carbon should be more reasonably expected to exist in the mantle of the Earth as an element in its dense phases: cubic (diamond), hexagonal (lonsdaleite), or random-close pack (chaoite).
