///Gas hydrates samples are successfully obtained by drilling in the Muli coalfield of Qinghai Province, which makes China the country which firstly discovers gas hydrate in the permafrost of the medium and low latitudes. The gas hydrates are preserved in the pores and cracks of the siltstone layers sandwiched in the oil shale member of the Middle Jurassic Jiangcang Formation. The gas in the gas hydrates is dominated by heavy hydrocarbons, with the methane accounting up to 52 %～68 %. In consideration of coalbed methane geology of the Muli Coalfield, the authors proposed that the coalbed methane is the main source of the gas in the gas hydrates in the Muli Coalfield and we name the gas hydrates “coal-prone gas hydrates”.
