Iron meteorite,Hexahedrite
Found in 1938; 7.275 kg
An iron meteorite (5.45% Ni) was acquired by the Griffith Observatory. The meteorite is a single kamacite crystal with Neumann bands and somewhat weathered, particularly along cubic cleavage fissures. Minor troilite, schreibersite, cohenite, and very minor daubréelite are also found. Rhabdite prisms are also oriented along the cubical structure. Twinned troilite also indicate previous plastic deformations. Daubréelite occurs within the troilite as parallel lamellae.
