Crystallographic analyses of clathrate hydrates included in Vostok ice cores
Purpose and methods of crystallographic analyses of clathrate hydrates included in ice cores recovered at Vostok, Antarctica are briefly reviewed. The clathrate hydrate is a crystal composed of a cage structure formed by water molecules, and includes individual air molecules in the molecular cages....
