Deformation bands

Material in a deformation band has a much smaller grain size, poorer sorting, and a lower porosity than the original sandstone.

They are common in the Colorado Plateau,[3] where examples occur in the Entrada Sandstone in the San Rafael Swell in Utah.

[1] Deformation bands are present in a variety of porous rock types such as sandstones, limestones, siltstones, poorly welded volcanic tuffs, and breccias.

[4] The Mars Reconnaissance Orbiter showed deformation bands in Capen Crater, located in the Arabia quadrangle.

The group of lines running up and down in the image are believed to be deformation bands. They can be thought of as small faults.
