NEA 104 (3.80 gram)

Classification: LUNAR troctolite melt breccia W-mod. / S-high
Place/Time: 2025 in Libya
Mass: 20kg

History: The meteorite was purchased from a dealer in Libya.
Physical characteristics: Several dark-grayish rocks with some fusion crust.
Petrography: The meteorite consists of a coarse- and a fine-grained lithology both predominantly composed of anorthosite clasts (coarse: up to 4 mm, fine up to 1.5 mm), olivine aggregates (coarse: up to 1.5 mm, fine up to 0.5 mm, and subordinate Ca-rich pyroxene grains set in abundant plagioclase-rich melt rock matrix. Anorthosite is partly transformend into maskelynite. While parts of the melt are glassy showing some flow textures, other regions are recrystallized to small often lath-shaped plagioclase crystals. Olivine aggregates are mostly composed of numerous subgrains with slightly variable composition. Ca-pyroxene appears to be more common in the coarse-grained lithology. Minor phases include chromite, ilmenite, and kamacite.
