Geologic map of the Aristoteles Quadrangle of the Moon

The Aristoteles quadrangle, located on the northeastern periphery of the Imbrium basin on the near side of the Moon, consist of four physiographic provinces: a northern mountainous belt, chiefly of lineated crater rims and other lineated terra; a middle-northern belt covered by mare material of Mare Frigoris; and a southern belt composed of mountainous material of diverse characteristics. The crat

Geologic map of the Clavius Quadrangle of the Moon

The Clavius quadrangle is in the southern lunar highlands about 500 km south of the Mare Nubium and 150 km south of the large young crater Tycho. This part of the Moon is characterized by densely cratered topography and the absence of mare materials. Geologic units in the quadrangle cannot be directly correlated with those in the vicinity of Mare Imbrium, 2500 km to the north, which define most of

Geologic map of the Cleomedes Quadrangle of the Moon

The Cleomedes quadrangle is broadly divisible into three provinces. First, the north half of Mare Crisium dominates the southern part of the area. Second, terra materials occur in concentric bands that alternate with mare or plains-forming materials in the northern part. These bands are interrupted by the crater Cleomedes whose associated materials dominate the northwest part of the map and form t

Geologic map of the Colombo Quadrangle of the Moon

Relative ages of structures and geologic units have been determined from intersection and apparent overlap relations and from morphologic freshness reflecting degree of preservation. The fivefold crater-age sequence is based on the classification of Shoemaker and Hackman (1962), and corresponds broadly to a modified classification of Pohn and Offield (1970) and Offield (1971). Rock units in the qu

Geologic map of the Eudoxus Quadrangle of the Moon

The Eudoxus quadrangle is in the northeastern part of the Moon’s nearside hemisphere. It is bordered on the west by Montes Caucasus, which form part of the main rim of the multi-ring Imbrium basin (Hartmann and Kuiper, 1962), and on the south side by Mare Serenitatis, which occupies another large multi-ringed basin. South and east of the prominent crater Eudoxus elevations decrease and the rugged
