NEA 138 is a feldspathic anorthosite breccia. It is a “puzzle” rock formed in the Moon’s highlands (the primitive, light-colored lunar crust). It consists of mineral fragments (such as anorthite, olivine, and pyroxenes) that were crushed, mixed, and fused together during violent asteroid impacts on the lunar surface.
This meteorite was discovered in Libya in 2026.
About fifteen years ago, lunar meteorites were sold for almost 1000 euros per gram !

Pallasites are meteorites composed of olivine crystals embedded in an iron-nickel matrix.
Main-group pallasites are considered to be fragments from the transition zone of a large differentiated asteroid (which had an internal structure similar to that of Earth, with an iron core and a rocky mantle). Pallasites are among the most visually striking meteorites.
Laayoune 002 is a very beautiful lunar meteorite discovered in the Western Sahara in 2022.
Space missions (such as Apollo or Luna) have brought back samples from very specific and limited geographic areas. Meteorites such as Laâyoune 002 come from areas that may never have been explored by humans, particularly the dark side of the Moon.

Mesosiderites are brecciated rocks containing silicate and metallic components, the silicates are mainly fragments of igneous rocks.
Writeup from MB 112:
Northwest Africa 15171 (NWA 15171)
Adrar, Algeria
Purchased: 2022
Classification: Mesosiderite
History: Bought by Jean Redelsperger from Mohamed Elguirah in 2022.
Physical characteristics: Many brown ireggular stones without fusion crust.
Petrography: (J.Gattacceca, CEREGE) The rock contains similar abundances of silicate minerals (pyroxene, and plagioclase), and metal and its weathering products. Silicate grain size is about 200 µm. Plagioclase and low-Ca pyroene dominate over Ca-pyroxene. Fe,Ni metal and troilite have been mostly replaced by terrestrial weathering products.
