Lunar mineralogy

How did lunar craters form? This issue has led to a long discussion between supporters of two hypotheses on the origin of lunar craters: volcanic and meteorite.

According to the volcanic hypothesis, which was put forward by the German astronomer Johann Schröter in the 80s of the 18th century, craters arose as a result of grandiose eruptions on the lunar surface. In 1824, his compatriot Franz von Gruutuisen proposed a meteorite theory that explained the formation of craters by the fall of meteorites.

Only 113 years later, in 1937, a Russian student Kirill Stanyukovich (future doctor of science and professor) proved that when meteorites strike at cosmic velocities, an explosion occurs, as a result of which not only a meteorite is melted, but also some of the rocks at the site of the impact. The explosive theory of Stanyukovich was developed in 1947-1960. by himself, and then by other researchers. Continue reading
