caption: The image shows a close up of a piece of rock on a white surface, which appears to be a pallasite, a type of meteorite. It is composed of a variety of stones, ranging from small, irregularly shaped stones to larger, more jagged stones. The stones are arranged in a pattern, with some of them overlapping each other, creating a unique texture. The colors of the stones range from light gray to dark gray, and the surface they are on is smooth and glossy.
