The Plato quadrangle in the north-central part of the Moon lies within a series of concentric depressed and raised rings surrounding the Imbrium basin, the center of which lies about 335 km southwest of Montes Teneriffe. The innermost raised ring is marked by isolated ridges and peaks within Mare Imbrium itself, including in the Plato quadrangle Montes Recti and Teneriffe. The band of...

The Pompeii quadrangle is in northern Maja Valles region between Lunae Palum to the west and Xanthe Terra to the east. Approximately two-thirds of the surface is a relatively smooth plain, and the other one-third is subdued, cratered, upland plateau. The crater Pompeii is the largest fresh crater in the quadrangle. The major interest in the map area is evidence of the relatively brief

The application of stratigraphic and structural principles to geologic mapping of the Moon from telescopic photographs has been discussed by Shoemaker (1962) and Shoemaker and Hackman (1962). Major geologic units are recognized by regional topographic and albedo differences. Pictures returned by Ranger, Surveyor, and Lunar Orbiter spacecraft show that a fragmental regolith, presumably...

The Purbach quadrangle is in the south central part of the lunar near side and includes the following four distinct topographic geologic provinces: 1) rugged and densely cratered highlands extending north south through the central part of the area locally dissected by large troughs (sculpture) of Imbrium age (Gilbert, 1893; Hartmann, 1963) 2) subdued terrain in the east where both...

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...

The Rima Hyginus region lies within the Mare Vaporum quadrangle (LAC 59), 7 degrees from the center of the lunar earthside hemisphere, near several large impact basins. The Rima Hyginus region occupies a broad structural trough concentric with the Imbrium basin, which has especially controlled the geology of the area, Plains-forming materials cover most of the region, except for a belt...

Material exposed on the surface of the moon is heterogeneous. The albedo and other physical characteristics that have been determined with the use of optical and radio telescopes vary from one part of the moon to another, and the variations are partially correlated with differences in topography . Discontinuities in the areal variation permit the surfaces material to be divided into map...

The Rumker quadrangle, in the northwest quadrant of the Moon, is adjacent to the western rim of the multi-ring Imbrium basin and to Sinus Iridum, a large (220 km diameter) mare-filled crater. Both of these great depressions were probably formed by impact, as indicated here and elsewhere on the Moon by the characteristic form, distribution, and texture of surrounding materials and...

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...

The Sappho Patera quadrangle (V-20) of Venus is bounded by 0 degrees and 30 degrees East longitude, 0 degrees and 25 degrees North latitude. It is one of 62 quadrangles covering the entire planet at a scale of 1:5,000,000. The quadrangle derives its name from Sappho Patera, a large rimmed depression (diameter about 225 km) lying on top of a shield-shaped mountain named Irnini Mons...

The Schickard quadrangle lies in the southwest quadrant of the near side of the moon between Mare Humorum to the northeast, the Orientale multi-ring basin 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 includes the 180 km wide crater Schickard, the most conspicuous...

Most images used in mapping the geology of the Shakespeare quadrangle were taken during the near-equatorial first pass, with close encounter on the dark side of the planet. The second, south-polar pass did not image the Shakespeare quadrangle at high resolution. High-resolution images of small areas within the quadrangle were also obtained during the third pass, when the spacecraft was...
