Classification: Eucrite S-low / W-moderate
Place/Time: 2023 in Libya
Mass: 1050 gram
Physical characteristics: Brownish rock with minor fusion crust.
Petrography: Achondritic breccia composed of fine-grained up to 2 mm sized angular to subrounded clasts set in more coarse-grained matrix, both showing metamorphic textures with some triple junction between adjoining minerals. Dominant phases in both lithologies are low-Ca pyroxene, Ca-pyroxene, and calcic plagioclase with grain sizes up to 80 µm in clasts and up to 300 µm in the matrix. Low Ca-pyroxenes are often exsolved in the matrix but not in the clasts and both, low-Ca pyroxene and Ca-pyroxene are more ferroan in the matrix compared to those in the clasts. Minor phases include ilmenite, chromite, FeS, and FeNi metal.
NOTE: Super polished from one side. Eucrite with enormous ammount of metalic iron.
