Abstract: This article discuss conditions of the mineralization of gas hydrate from geology,believes that this area has a good condition of mineralization of gas hydrate in the continental slope of the East China Sea. By distinguishing the data of multichannel seismic reflection profile and high resolution seismic profile of several ten lines in the continental slope areas,we have divided where the gas hydrate resources exist,and estimated the amount of reserve of gas in the places. All these provide a good opportunity of seeking mineral resources of gas hydrate in the area and calculating prospect of gas hydrate resources in the future.
