NWA 16802 Meteorite Specimen Official H5 Melt Breccia Northwest Africa Meteorite

An authentic specimen of the officially classified Northwest Africa 16802 (NWA 16802) meteorite, a rare H5 melt breccia approved in Meteoritical Bulletin 114 in 2025. Recovered in Morocco and weighing a total of 8.9 kilograms, this meteorite displays dramatic melt-breccia textures highly sought after by advanced meteorite collectors.

NWA 16802 is especially notable for its striking visual structure, featuring large pale brown chondritic clasts suspended within a dark melt-rock matrix rich in visible metallic phases. The contrasting textures and impact-processed appearance make this meteorite an outstanding display and study specimen.

Scientific Composition

Scientific analysis identified: brecciated chondritic structure, large pale brown clasts, dark melt-rock matrix, visible Fe-Ni metal throughout, metal-rich veins within clasts, chromite, ilmenite, sodic plagioclase, and Ca-phosphate grains.

Physical Characteristics

Official reports describe: visible but poorly defined chondrules, abundant melt textures, contrasting clast and matrix structures, and strong metallic content throughout the stone.

Geochemical Data

• Olivine Fa19.4±1.2
• Pyroxene Fs16.4±1.7 Wo1.6±0.7

Condition

Please review all photos carefully for overall condition, melt textures, fractures, oxidation, weathering, and surface characteristics, as they are considered part of the description. Meteorites are natural extraterrestrial objects and commonly display structural variation, impact-related fracturing, oxidation, and atmospheric features.
