Abstract
    Based on gas-hydrate distribution and carbon isotopic compositions of abiogenic methane under hydrothermal conditions, it is shown that gas-hydrate might be a hydrothermal hydrocarbon which is formed by inorganic synthesis. A special hydrocarbon formation model is presented. The exploration prospect of natural gas hydrate in China offshore is reviewed.
