Impact melt breccia is a type of rock formed during meteorite impacts on planetary bodies such as the Moon, Mars, and Earth. It is characterized by a matrix of solidified impact melt containing fragments of pre-existing rocks and minerals that were incorporated into the melt during the impact event. Impact melt breccias provide valuable information about the processes and conditions involved in large impacts, such as shock metamorphism, melting, and mixing of materials from different depths within the target rock. Studying impact melt breccias can help researchers understand the dynamics of impact events and the geological history of planetary surfaces.
