Geologic map of the Rheita Quadrangle of the Moon

Photographs returned by unmanned Lunar Orbiters have contributed greatly to the current lunar geologic mapping program. This is particularly true for quadrangles near the limbs, such as Rheita in the southeast earthside quadrant. The new data and revised interpretations amend the geologic framework established by earlier workers (Shoemaker (1962) and Shoemaker and Hackman (1962) applied basic stra

Geologic map of the Rupes Altai Quadrangle of the Moon

The Rupes Altai quadrangle of the Moon is in the rugged, cratered terra of the southeastern earthside hemisphere. East-northeast of the quadrangle lies Mare Nectaris, approximately 350 km in diameter, and near the northeast corner is the crater Theophilus. Rupes Altai (the Altai scarp) divides the quadrangle into two markedly different morphologic provinces. To the west, complexly overlapping, fra

Geologic map of the Sabine EB region of the Moon

The Sabin EB region is a rolling plain which consists entirely of crater and mare materials. The areal density of craters, though variable within the region, is sufficiently high so that the craters are the dominant morphological feature. Crater morphology ranges from bright, sharp-rimmed craters to pan-shaped depressions. Superposition relations indicate that the bright-rimmed craters (unit br) a
