Geologic map of the Tycho Quadrangle of the Moon

The Tycho quadrangle is centrally located in the southern half of the earthside hemisphere of the Moon. The area is characterized by a high density of craters, the largest of which – Stofler – is about 140 km in diameter. The northern and eastern parts if the quadrangle are dominated by plains (pIp, Ip) and hilly terra (IpIt) units of regional extent, and the western part by the crater Tycho and its ejecta blanket. Structural features probably associated with the Imbrium basin to the north and Orientale and Humorum basins to the northwest are present, although blanketing units related to these basins are not recognized.
