Geologic map of the southeast quarter of the Priest Valley quadrangle, Fresno and Monterey Counties, California

No abstract available.

Geologic map of the Taruntius Quadrangle of the Moon

The distribution of major physiographic provinces and geologic units of the Tarantius quadrangle is determined by the five intersecting circular multi-ringed mare basins. Three basins, in probable order of decreasing age, are Tranquillitatis, Fecunditatis, Serenitatis, Nectaris, and Crisium. The uplifted ring structures of the basin form terra mountains, peninsulas, and islands, and the depression

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 i

Geologic maps of the Descartes region of the Moon Apollo 16 pre-mission maps

The evolution of the Moon’s surface shows three successive stages (Hartmann, 1970). The earliest, from the beginning of the decipherable record to the Imbrian Period, was dominated by frequent large-scale impacts which produced overlapping and interfering craters and giant multi-ringed basin with ejecta blankets. The second stage, extending through most of the Imbrian to early Eratosthenian Period

Geologic maps of the Taurus-Littrow region of the Moon Apollo 17 pre-mission maps

The Taurus-Littrow region is mainly a highland area at the juncture of Mare Serenitatis and Mare Tranquillitatis (Scott and Pohn, 1972). Highland materials cover most of the area, forming a group or rugged massifs close to the center of the map and more subdued terrain to the east. The highland units (pItm, IpIh) are probably mostly breccias formed by the Serenitatis impact and pre-existing brecci
