单词 | wrinkle ridges |
释义 | wrinkle ridgeswrinkle ridgesLinear deformed and folded lunar features that are confined to the maria and may be elevated by several hundred meters; they may however continue into the highlands as scarps. Wrinkle ridges are frequently compound, discontinuous, and associated with rilles. They often reflect underlying topography, including basin ring structures beneath the maria. They may result from fissure eruptions, faulting, or the contraction of a surface crust following the draining away of subsurface lavas. Surveyor 6 landed close to a wrinkle ridge in Sinus Medii.
