Geological studies of the Moon are based on a combination of Earth-based telescope observations, measurements from orbiting spacecraft, lunar samples, and geophysical data. . Six locations were sampled directly during the crewed Apollo program landings from 1969 to 1972, which returned 382 kilograms (842 lb) of lunar rock and lunar soil to Earth [8] In addition, three robotic Soviet Luna ...
The Procellarum KREEP Terrane, or PKT, is a large province on the near side of the Moon that has high abundances of KREEP.KREEP is an acronym built from the letters K (the atomic symbol for potassium), REE (rare-earth elements) and P (for phosphorus), [3] and is a geochemical component of some lunar impact breccia and basaltic rocks.

[1] [2] Potential lunar resources may encompass processable materials such as volatiles and minerals, along with geologic structures such as lava tubes that, together, might enable lunar habitation. The use of resources on the Moon may provide a means of reducing the cost and risk of lunar exploration and beyond. [3] [4] [5]
The modern system of lunar nomenclature was introduced in 1651 by Giovanni Battista Riccioli. [1] Riccioli's map of the Moon was drawn by Francesco Maria Grimaldi, who has a crater named after him. A related set of features are the Lunar lacus / ˈ l eɪ k ə s / (singular also lacus, Latin for "lake"), [a] which are smaller basaltic plains of ...
Lacus Somniorum (Latin somniōrum, "Lake of Dreams") is a basaltic plain located in the northeastern part of the Moon's near side. It is located at selenographic coordinates 37.56° N, 30.8° E, and has a diameter of 424.76 kilometers. [1] The name is Latin for Lake of Dreams, a title given to this feature by Giovanni Riccioli.

The Pre-Nectarian period is defined from the point at which the lunar crust formed, to the time of the Nectaris impact event. Nectaris is a multi-ring impact basin that formed on the near side of the Moon, and its ejecta blanket serves as a useful stratigraphic marker. 30 impact basins from this period are recognized, the oldest of which is the South Pole–Aitken basin.
