Description
A dark reddish-brown, irregularly shaped H5 chondrite stony meteorite, exhibiting a distinct fusion crust with visible flow lines and signs of melting on its surface.
Geological Context
Formed in the early solar system from the accretion of dust and pebbles in the asteroid belt, subsequently undergoing thermal metamorphism on its parent body. It fell to Earth after traveling through space, developing a fusion crust during atmospheric entry.
