Gas Hydrates in the Qilian Mountain Permafrost, Qinghai, Northwest China
Abstract: Qilian Mountain permafrost, with area about 10×10 4 km 2 , locates in the north of Qinghai‐Tibet plateau. It equips with perfect conditions and has great prospecting potential for gas hydrate. The Scientific Drilling Project of Gas Hydrate in Qilian Mountain permafrost, which locates in Ju...
