Beethoven quadrangle [SEP] located on astronomical body
Beethoven quadrangle
The Beethoven quadrangle is located in the equatorial region of Mercury, in the center of the area imaged by "Mariner 10". Most pictures of the quadrangle were obtained at high sun angles as the "Mariner 10" spacecraft receded from the planet. Geologic map units are described and classified on the basis of morphology, texture, and albedo, and they are assigned relative ages based on stratigraphic relations and on visual comparisons of the density of superposed craters. Crater ages are established by relative freshness of appearance,
