Raditladi Basin is a large peak ring impact crater on Mercury with a diameter of about 250 km. Inside its peak ring there is a system of concentric extensional troughs (graben), which are rare surface features on Mercury. The floor of Raditladi is partially covered by relatively light smooth plains, which are thought to be a product of the effusive volcanism. The troughs may also have resulted from volcanic processes under the floor of Raditladi. The basin is relatively young—probably younger than one billion years, with only a few small impact craters on its floor and with well-preserved basin walls and peak-ring structure.
