Has anyone studied the impact structure? I am referring not only to the ring structure of the earth's surface. I would like to understand and study the structural features and morphologies similar to the destruction and formation of rock formations below the surface of meteorites. I published an article in June this year, some of which is about the structure of the impact structure. Can friends help me find or provide information on the study of impact structures? For example, the impact structure is formed below the impact point in terms of fracture structure characteristics, shape, size, and the like. thank you very much.
