Sedimentology and Stratigraphy. In radioactive decay, an element breaks down into another, lighter element, releasing alpha, beta, or gamma radiation in the process. Cosmic ray dating is only useful on material that has not been melted, since melting erases the crystalline structure of the material, and wipes away the tracks left by the particles.
