AI-assisted summary
Description from the seller
This is a high-quality 50 gram end cut of Northwest Africa 17755, an officially classified CV3 carbonaceous chondrite now offered for sale. The total known mass is only 500 grams, making this roughly 10% of the main mass.
The petrographic examination of NWA 17755 revealed a particularly interesting assemblage of porphyritic olivine (PO) and porphyritic olivine-pyroxene (POP) chondrules, together with calcium-aluminium-rich inclusions (CAIs) and amoeboid olivine aggregates (AOAs). These refractory components comprise approximately 5–10 vol.% of the examined material.
The chondrules have an average diameter of approximately 0.8 ± 0.5 mm, based on 42 measured chondrules. They are embedded within a clastic matrix comprising approximately 40 vol.% of the meteorite, giving NWA 17755 its characteristic heterogeneous CV3 texture.
The refractory inclusions preserved in NWA 17755 are particularly significant. CAIs are among the oldest recognisable solids formed in the Solar System, while AOAs represent another class of refractory material formed during high-temperature processing of the early solar nebula. Their preservation alongside primitive chondrules and a relatively abundant clastic matrix makes CV3 chondrites valuable records of the processes that occurred before the formation of the planets and differentiated asteroids.
The polished face reveals the characteristic contrast between the darker matrix and the numerous embedded chondritic components, while the presence of refractory inclusions and chondrules makes this an especially interesting specimen for collectors of primitive carbonaceous chondrites.
CV3 chondrites are among the most scientifically important chondritic meteorites because they preserve material formed during the earliest stages of Solar System evolution, before extensive thermal metamorphism substantially modified their original mineralogical characteristics.
