Nogoya, Historic 1879 Second CM Fall, Argentina, Micromount

Adding to cart… The item has been added

On June 30, 1879, a uniquely-luminous fireball was seen over the Nogoya area of rural Argentina. A single small stone about 4kg was recovered. Analysis revealed this dark, coal-like meteorite to be a carbonaceous chondrite of the CM2 type. Historical accounts of this fall are scant in the record, but it has also been referred to as the “Concepcion” meteorite.

Nogoya is the second oldest CM2 witnessed fall after Cold Bokkeveld in South Africa in 1838. Surviving fragments of this meteorite were studied by scientists and found to contain evidence of free organic radicals, which is suggestive of biogenic activity (source : NASA, Free Organic Radicals in the Mighei and Nogoya Meteorites, by Duchesne.)

Very little of this meteorite exists on the private market and it is rarely offered to collectors. I acquired a small amount for my personal collection and this is the first time I have ever offered any. Don’t miss this chance to add this historical CM2 fall to your collection.
