“…It has been proposed that carbonate reduction at mantle conditions may be important for the production of abiogenic methane in the Earth's interior (Scott et al, 2004;Chen et al, 2008). Evidence presented to support this suggestion is based on methane formation in a diamond-anvil cell after FeO + CaCO 3 + H 2 O was subjected to temperatures between 500 and 1500°C and pressures between 5 and 11 GPa in a diamond-anvil cell using a spring steel gasket in both laser-heating and resistive-heating experiments.…”

What will happen when methane is at a temperature of 1500 K? On the first glance the answer seems to be obvious ‐ methane will decompose into hydrogen and one of the forms of carbon. Yes. However is does not do so at very high pressure, when novel reaction pathways become possible. The latest experimental results and theoretical calculations show that methane and heavier hydrocarbons are, remarkably enough, stable under extreme pressures and temperatures. Even more, experiments confirm the possibility of abiogenic synthesis of natural gas at 5.0 GPa and 1500 K. The review summarizes published results of theoretical and experimental investigations of possible pathways under the conditions of pressure and temperature that prevail in the Earth's upper mantle for the formation of (1) particular species of hydrocarbon molecules, and of (2) complex hydrocarbon systems. The results raise fundamental questions on the genesis of hydrocarbons.

“…In other efforts to investigate formation of hydrocarbons in the mantle, several recent experimental studies have examined the production of CH 4 and other light hydrocarbons when calcite (CaCO 3 ) is exposed to mantle pressures and temperatures under reducing conditions (Kenney et al 2002;Scott et al 2004;Chen et al 2008b;Sharma et al 2009;. These experiments have been conducted at temperatures of 500-1500 °C, and pressures from 1 to 11 GPa.…”
