Preliminary geologic map of the Schickard Quadrangle of the Moon

The Schickard quadrangle lies in the southwest quadrant of the near side of the moon between the Humorum mare basin to the northeast, the Orientale basin multi-ring structure to the northwest, and the crater Tycho to the east. A northward trending arcuate chain of large craters occurs along the south and west margins of the quadrangle and appears to include the crater Schickard. The geology of the quadrangle should therefore record episodes related to the development of these nearby major lunar features considered to represent earliest (pre-Imbrian) to latest (late Copernican) events in the geologic history of the moon.
