(chemistry)
An inclusion compound in which the guest species is enclosed on all sides by the species forming the crystal lattice. Also known as cage compound; inclusion compound.
(geochemistry)

Clathrate is an icelike material itself in which water molecules form ``cages'' that have gas molecules trapped in them, in this case methane or natural gas.

If this is so, methane might be released from its clathrate cages during the eruptions of proposed 'cryovolcanoes' of water-ammonia slurry, or more simply could slowly seep out through fractures in the crust.
All of the cages are not necessarily dependent on the temperature and the pressure of the guest compound in equilibrium with clathrate hydrate.
