1. "The Caloris Basin is thought to be similar to the large circular basins found on the moon. Probably formed by a giant impact early in Mercury's history, this basin was subsequently filled by lava flows. The nature of the wrinkle ridges on its floor is arguable: some scientists claim tectonics while others suggest they are due to volcanic flows escaping from fractures."

The Caloris basin was probably the result of a large asteroid collision.  It is surrounded by concentric mountain ranges.  On the opposite side of Mercury is rippled pattern possibly formed by seismic waves that traveled completely around Mercury as a result of this impact.
