Review of published geological data shows that permafrost regions in China's Mohe Basin, Qilian Mountain, and Qinghai‐Tibet Plateau hold promise for gas‐hydrate accumulation according to identifiable source rock, migration path, and reservoir seal, among others.

However, formation lithology, source‐rock type, origin of organic matter, and total organic carbon (TOC) exhibit significant differences.
