The structure and texture of these fragments indicate they were formed by a very intensive melting process, due to collision or close proximity to the sun. The researchers explained this material is very distinct from the ‘fusion crust’ – a thin layer of material on the surface of the meteorite that melts and solidifies as it barrels through our atmosphere.
