According to the amounts of released gas upon decomposition, methane hydrates have different distribution features in silty sand and in clay. In silty sand, methane hydrate has a very high saturation rate (>80% of pore space), and almost the same gas release rates from the column edge to the center indicating that hydrate is homogeneously ...
