What kind of rock is the moon made of?
The composition of the rocks on the moon based on samples of lunar rocks are volcanic in origin. The rocks are basalts, similar to the kind of volcanic rock found on Earth. The lunar basalts are rich in iron and magnesium, and they also contain glassy structures that are indicative of rapid cooling. However, unlike Earth basalts, the lunar samples contain no water and a lower percentage of volatiles (elements or compounds with low melting and boiling temperatures) relative to refractories (higher melting and boiling temperatures).
