Lot 873
Rare Slice of a Silicated NWA 5549 Iron-Nickel Meteortie. All silicated Iron-Nickel meteorites are very rare and important because they match up with oxygen isotopes with the also rare primitive achondrites like Winonaite. Most stony meteorites are chondrites meaning that they have round chondrites in their make up. Achondrites lose most of their original chondrites because of metamorphism and partial melting. This sizeable 101.4 grams 2x13/4 inch partial slice of NWA 5549 found in Algeria in 2008 has been polished and etched showing many silicate inclusions in the iron-nickel fields. The silicate inclusions are chondritic in chemical composition but being recrystallized makes them an achondrite. Matching up with Winonaite means that the IAB NWA 5549 originated from the same parent body. Winonaites came from closer to the surface and NWA 5549 from deeper in the core of the yet to be discovered planetesimal body. Estimate Value $1,000 - UP
