The lower pT limit of deep hydrocarbon synthesis by CaCO3 aqueous reduction

Abstract The deep abiogenic synthesis of hydrocarbons is possible under the conditions of the asthenosphere. We have found that this process can also occur under the mineral and thermobaric conditions of subducting slabs. We have investigated the abiogenic synthesis of hydrocarbon systems at pressur...
