The nature of the lunar surface
Flying the Apollo "helped us understand what makes up the lunar surface. It is composed primarily of basalt, is unusually rich in iron and titanium. Bark as a whole are represented by different types of rocks with inclusions of feldspar, pyroxene and olivine in varying proportions, and some other materials such as spinel, ilmenite, apatite and zircon. Most of the Moon was formed complex silicates. Aluminum at greater heights. Radioactivity apparently associated with low-lying parts. The lowest radioactivity on the moon noted in the uplands, located at the periphery of the visible disk of the moon.
If you equip the moon base, then the problem can be solved with oxygen: about two and a half tons of iron ore through the restoration can get a ton of oxygen. And this - a three-year supply of oxygen for an earthling. (Perhaps this is why they are destroying the mountains? "They, like we need oxygen to astronauts of" Apollo-17 "found in the crater of orange rock. Everywhere the surface was black, red and orange glass beads. Nobody knows exactly how to go horrible stained glass, but it can be assumed that the meteorite hit a lot of warm and of silicate glass is formed.
Surprisingly, the soil is not the same on the surface of the moon: it varies from hills to lowlands and from place to place.
