NEA 089, Lunar troctolitic anorthosite melt breccia. A very interesting classification; there are only a few of this type. - 2 g

Lunar troctolitic anorthosite melt breccia represents a rare type of lunar rock, combining features of anorthosite and troctolite with a brecciated texture caused by melting and solidification. Such moon rocks are of great scientific interest as they reveal insights into the Moon’s geological history and surface processes. Anorthosites are predominantly composed of plagioclase feldspar, indicating formation from crystallized magma in the lunar crust, while troctolites have both olivine and plagioclase. The brecciated nature suggests it has undergone impact-induced melting and fragmentation, documenting harsh conditions on the lunar surface. Samples like these are highly collectible and valuable for researchers and space enthusiasts, as only a few specimens are known and classified. Weighing about 2 grams, this particular piece would be a representative fragment illustrating lunar magmatic and impact history.
