1.12" OC4 Melt Breccia Chondrite Meteorite (21 g) - NWA 15878
This is a 1.12" wide (21 gram) meteorite from the NWA 15878 fall which was discovered recently in 2023. It retains most of its fusion crust meaning it is likely a fairly recent fall.
About Meteorite NWA 15878
Northwest Africa (NWA) 15878 is a stony meteorite found in Northwest Africa (Morocco) in 2023, with the total known mass around 70 kg recovered from the Sahara Desert and later made available through dealers there. It is officially classified as an ordinary chondrite OC4 “melt breccia” (shock stage S2 / weathering W1) in the Meteoritical Bulletin Database. This classification means it’s part of the most common class of meteorites—ordinary chondrites, which are primitive rocks from asteroid parent bodies containing small, once-molten spheres called chondrules—but in this case the material has also been partially melted and brecciated (broken and re-welded) by past impact events on its parent asteroid. OC4 indicates a moderate degree of thermal metamorphism relative to other ordinary chondrites, and “melt breccia” reflects a history of shock/impact processing that mixed melted fragments with older material as the meteoroid’s parent body was fractured and rehealed.
