Wrinkle-ridge
From Wikipedia, the free encyclopedia
A wrinkle-ridge is a type of feature commonly found on Lunar mares. These features are low, sinuous ridges formed on the maria surface that can extend for up to several hundred kilometers. The wrinkle-ridges are tectonic features created when the basaltic-lava first cooled and contracted. They frequently outline ring structures buried within the mare; follow circular patterns outlining the mare, or intersect protruding peaks. They are sometimes called veins due to their resemblance to the veins that protrude from beneath the skin.
Wrinkle-ridges are named with the Latin designation dorsum (plural dorsa). The standard IAU nomenclature uses the names of people to identify wrinkle-ridges on the Moon. Thus the Dorsa Burnet are named for Thomas Burnet, and the Dorsum Owen is named after George Owen of Henllys.
Wrinkle-ridges can also be found on Mars, for example in Chryse Planitia, as well as on several of the asteroids that have been visited by spacecraft, as well as Mercury, and a couple of moons of Jupiter and Saturn.
