| 摘 要： | In order to investigate the mechanism of formation of abiogenetic hydrocarbons at the depth of the Earth,experimental research on reactions between carbonates and water or waterbearing minerals was carried out at the pressure of about 1GPa and the temperature range of 800-1500℃.The reactions took place in an open and nonequilibrium state.Chromatographic analyses of the gas products indicate that in the experiments there were generated CH4-dominated hydrocarbons,along with some CO2 and CO.Accordingly,we think there is no essential distinction between free-state water and hydroxy in the minerals in the process of hydrocarbon formation.This study indicates that reactions between carbonates and water or water-bearing minerals should be an important factor leading to the formation of abiogenetic hydrocarbons at the Earth‘s depth.

| Abstract: | In order to investigate the mechanism of formation of abiogenetic hydrocarbons at the depth of the Earth, experimental research
on reactions between carbonates and water or water-bearing minerals was carried out at the pressure of about 1 GPa and the
temperature range of 800–1500°C. The reactions took place in an open and nonequilibrium state. Chromatographic analyses of
the gas products indicate that in the experiments there were generated CH4-dominated hydrocarbons, along with some CO2 and CO. Accordingly, we think there is no essential distinction between free-state water and hydroxy in the minerals in the
process of hydrocarbon formation. This study indicates that reactions between carbonates and water or water-bearing minerals
should be an important factor leading to the formation of abiogenetic hydrocarbons at the Earth's depth.
