The LRO mission support group has published a new image of the Moon. It demonstrates a wrinkle ridge — a mountain formation located on the northern edge of the Mare Imbrium.
A wrinkle ridge is a linear structure oriented in the direction from west to east. That’s why it got its name. The formation is 90 km long, 20 km wide, and the maximum height of its mountains reaches 1.8 km.
It is believed that the wrinkle ridge is part of the inner shaft of a giant crater that gave birth to a Mare Imbrium. Later it was almost completely filled with lava. As a result, only the highest parts of the shaft remained on the surface. The ridge is of some scientific interest. The slopes of its mountains are composed of rocks dislodged from the lower part of the lunar crust during the formation of the crater. Presumably, they contain a high concentration of titanium and iron.
In addition to the wrinkle ridge, one of the characteristic ridges that are often found in the lunar seas also fell on the LRO image. Their length can reach hundreds of kilometers. It is believed that such formations were formed during the processes that accompanied the solidification of lava fields on the Moon.
Recall that earlier we published a mosaic of the Moon, made up of images of the LRO mission.
