The Mohe Basin in Heilongjiang, China has a NEE thrust nappe belt, which was assembled by the root zone, middle thrust zone and thrust front, north-south and north-east normal faults with three tectonic activities of the Middle Jurassic to Eocene, the Miocene, and the Early to Middle Pleistocene. The middle thrust zone and thrust front has a large number of folds, thrust faults, fractures and glutenites, which are the major structures of gas hydrate accumulation in the Mohe Basin.
