meteorite rafsa 007 Angrite - 0.47 g

Object: Acondrite meteorite (Angrita)
Official name: Rafsa 007
Place of discovery: Tinduf Region, Algeria
Year of discovery: 2023
Classification: Angrita (officially approved)

This specimen is an acondrite meteorite from the Angrita group, officially classified as Rafsa 007, found in the Tinduf region, Algeria, in 2023. It is not an observed fall but a field find, and it is registered and approved in the Meteoritical Bulletin, confirming its scientific authenticity.

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

The surface displays dark shades, ranging from brown to black, with moderate soil alteration visible as reddish-brown spots. The texture is rough and heterogeneous, with evident 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 piece has not been polished, restored, or subjected to any artificial treatment, and it is presented in the natural state in which it was recovered.
All observable characteristics are considered natural defects, resulting from fragmentation processes, environmental exposure, and recovery, rather than 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, standing out both for its scientific value and its uniqueness.
