Wrinkle ridge

A wrinkle ridge is a type of feature commonly found on lunar maria, or basalt plains.

These features are low, sinuous ridges formed on the mare surface that can extend for up to several hundred kilometers.

The standard IAU nomenclature uses the names of people (generally scientists) to identify wrinkle ridges on the Moon.

Wrinkle ridges can also be found on Mars, for example in Chryse Planitia, on several of the asteroids that have been visited by spacecraft, on Mercury, and certain moons of Jupiter and Saturn.

Although several hypotheses have been advanced as causes of wrinkle ridges, today they are generally considered to be of tectonic origin.
