This 109-gram specimen is a verified piece of NWA 18759. Classified as an L5 chondrite, it provides clear evidence of thermal metamorphism within its parent asteroid. Scientifically, this specimen is characterized by "equilibrated" olivine and pyroxene minerals and the presence of secondary recrystallized plagioclase. These features indicate that the rock was subjected to prolonged heating in the early solar system, distinguishing it from more primitive, unaltered meteorite types.
