NWA 4860 is a L4 chondrite with highly shocked chondrules, a feature of a violent history. Highly shocked meteorites are always interesting to science as they give researchers a glimpse into a moment of great impact, heat and pressure. It has a shock stage of S6 and contains melt rock that surrounds chondrules and fragments in the structure. The metal in the meteorite is visually unusual and the meteorite has a light scattering of bubbles. This is definitely a unique meteorite with lots of interesting features. The slices are highly polished on one side.
