Saint-Pierre-le-Viger

The Saint-Pierre-le-Viger meteorite is an ordinary chondrite of the L5-6 class , which was observed in its fall on 13 February 2023 in the Normandy region of France. The meteorite's fall was part of the trajectory of asteroid 2023 CX1, discovered by Hungarian astronomer Krisztián Sárneczky. The first fragment, weighing 94 grams, was found by art student Loïs Leblanc-Rappe in the commune of Saint-Pierre-le-Viger during an organised search.

This meteorite has a chondritic structure, brecciated in places, with a predominance of olivine and low-calcium pyroxene (orthopyroxene). Chondrules are rare or completely absent in the samples, due to the high petrological type. It also contains plagioclase, troilite, Fe-Ni metal, chromites and phosphates, including apatites and merrillites. Of interest is the presence of shock veins and a high-pressure phase of jadeite, indicating a C-S3 shock grade
