Introduction

Shock waves have been important in the history of virtually all meteorites. Recent studies of melt veins in meteorites have indicated that many meteorites were deep within a parent body at the time of shock metamorphism. We have recently realized that it is virtually impossible for a meteorite to survive strong shock unless it is well below the surface of a parent body. The unconfined compressive strength of the strongest rocks is only about 500 MPa. To survive a stronger shock without being pulverized, the rock must be confined by surrounding material.
