The lighter highland rocks are calcium-rich, metal-poor anorthosites
, the original lunar crust.
A norite-based binder has been successfully produced from the waste tailing of an ilmenite mine consisting mainly of anorthosite
. The particle size of the source material significantly affected the reactivity.

complex and associated meta-volcanic rocks, SW Greenland: evidence for a magmatic origin.
The new analysis of ferroan anorthosite
(FAN) moonrock samples is published today in the journal Nature.
(165) Data from the Orbiter showed that the lunar highlands have more variation in their chemical composition than previously thought, and detected minerals richer in sodium than the typical anorthosite

Several regions of the world with similar rapakivi-like granites have formed during crustal extension where crustal rocks are believed to have been mixed with magma from below, resulting in the formation of anorthosite
and granite (Lyckberg, 2009).
Just like the rocks on Earth, Moon's have lots of basalt and olivine, pyroxene, and mafic breccias, along with plagioclase feldspar, also known as anorthosite
. The crew of Apollo 11 even found an entirely new mineral at Tranquility Base during their 1969 visit - dubbed armalcolite in honor of astronauts Neil Armstrong, Buzz Aldrin and Michael Collins.
The use of this technology has been assessed with two minerals, anorthosite
(a calcium alumino-silicate) and jotunite (an iron-rich basalt).
