Geologic maps of the Descartes region of the Moon Apollo 16 pre-mission maps 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...
Geologic maps of the Taurus-Littrow region of the Moon Apollo 17 pre-mission maps Geologic maps of the Taurus-Littrow region of the Moon Apollo 17 pre-mission maps

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...
