Shock metamorphism or impact metamorphism describes the effects of shock-wave related deformation and heating during impact events. The formation of similar features during explosive volcanism is generally discounted due to the lack of metamorphic effects unequivocally associated with explosions and the difficulty in reaching sufficient pressures during such an event. WitrynaThe material characteristics of lunar materials are discussed as indicators of shock metamorphism. As lunar materials are subjected to both impact shock modification due to energetic particles formed at locations of collisionless plasma shocks in cosmic space, it is necessary to identify specific features of each process. All types of lunar glasses …
