A new type of chondrite meteorite has just been discovered; it is not an H, L or LL type chondrite.
This new type has been named OC4 (ordinary chondrite of petrological type 4). This meteorite contains a high proportion of metal and its cross-sections are very attractive.

NWA 18131 is a 220-gram ordinary chondrite of the L6 type.
It was discovered in July 2025 in Morocco in the Chwichiya concentration zone by Elguirah El Houssine near the site where NWA 7831, a diogenite achondrite, was found.
A magnificent collector’s item, this unclassified chondrite was discovered in the Sahara, most likely in Morocco.
What makes this piece unique is its weight, but also the regmaglypts on its surface.
Regmaglypts are hollow indentations, often thumb-shaped, found on certain meteorites.
Entering the atmosphere slows down the trajectory of meteorites due to air friction.
This friction tears off pieces, forming regmaglypts.
Jdiriya 004 is a rare and fresh rumuruti R3 chondrite weighing only 142 grams.
Magnetic susceptibility, chondrule diameters, mineral chemistry and texture suggest that it is an R3-4 breccia.
Only 10 meteorites of this type are classified to date.
The R chondrite group does not clearly belong to any of the major chondrite classes (ordinary, carbonaceous, enstatite); R chondrites have sub-solar Mg/Si and refractory/Si ratios, oxygen isotopic compositions that are above the terrestrial fractionation line and ordinary chondrites, and strongly oxidized mineralogy.
The first R chondrite, Carlisle Lakes, was found in Australia in 1977.
