Crater chain

As Catena (Latin, plural Catenae translated, "chain" ) or chain of craters are in the Planetary Geology called linear surface structures on planetary celestial bodies, specifically those which consist of a series of smaller impact craters.

Logging was larger meteorites often arise so-called secondary craters formed by the impact flung out material. Often these are linearly arranged to form a chain. Crater chains can be caused by tidal forces ripped larger bodies but also by the impact of individual parts. Since the causes of the formation of linear structures but it is not always clear and sometimes the time of the designation set the available resolution a more accurate identification of boundaries, Catenae can also be volcanic (eg remains of collapsed lava tubes ) or tectonic origin.
