meteorite rafsa 007 Angrite - 0,47 g

Subject: Angrite Meteorite Acondrita (Angrita)
Official name: Rafsa 007
Place of discovery: Tindouf Region, Algeria
Year of discovery: 2023
Classification: Angrite (officially approved)

This specimen is an acondrite meteorite of the Angrite group, officially classified as Rafsa 007, found in the Tindouf region, Algeria, in 2023. It is not a meteorite fall with observed meteorites, but a field discovery, and it is registered and approved in the Meteoritical Bulletin, which confirms its scientific authenticity.

The meteorite is composed of an ultramafic differentiated igneous rock, with a well-defined granular texture, formed mainly by calcium-rich olivine, pyroxene (diopside), chromium-rich spinel and anorthite. This mineral composition is characteristic of angrites, one of the rarest and oldest groups of meteorites known, formed from evolved magmas in a primitive planetary body.

The surface presents dark hues, ranging from brown to black, with moderate terrestrial alteration, visible as reddish-brown patches. The texture is rough and heterogeneous, with obvious natural fractures, angular edges and small surface fissures. No visible fusion crust is preserved, a circumstance attributed to natural erosion following the fall, common in desert finds of this type.

The specimen has not been polished, restored, or subjected to any artificial treatment, and is presented in the natural state in which it was recovered.
All observable features are considered natural defects derived from fragmentation, environmental exposure, and recovery processes, and not from human manipulation.

Overall, Rafsa 007 is an authentic angrite meteorite, extremely rare and scientifically documented, of high interest to specialized collectors and studies of differentiated planetary materials, highlighting its scientific value and uniqueness.
