wrinkle ridge

Astronomy
  • A meandering ridge on a planetary surface that resembles a wrinkle in skin or cloth. Wrinkle ridges were first named on the Moon, but are found on all the terrestrial planets and many large satellites. They are thought to arise from some combination of subsurface faulting and compression.

A broad, curvilinear swell up to 500 m high and 10 km wide, topped by a narrow, steep-sided ridge up to 200 m high and 2–4 km wide, extending for tens to hundreds of kilometres concentrically near the edges of lunar mare basins.
