(LAC-38) Geologic map of the Seleucus quadrangle of the moon

The Seleucus quadrangle lies in the northwestern part of the Oceanus Procellarum, a large mare of irregular shape in the western part of the earthside hemisphere of the Moon. Material of the mare occupies most of the quadrangle. Craters ranging from 1 to 44 km in diameter are scattered over the smooth mare surface; in addition, a few isolated hills and ridges rise above the mare. In the east-central part of the quadrangle, the Aristarchus plateau (informal name) slopes gently westward and merges with the surrounding surface of Oceanus Procellarum. The plateau is also known for its reddish color and light absorption properties (Wood, 1912), and areas where occasional reddish glows have been seen (Greenacre, 1965).
