Impact Melt Rock

Rock that has been made temporarily molten as a result of the energy released by the impact of a large colliding body. Impact melts include small particles, known as “impact melt spherules” that are splashed out of the impact crater, and larger pools and sheets of melt that collect in low areas within the crater. Melts are composed predominantly of the target rocks, but can contain a small but measurable amount of the impactor.
