NMM 2045 - Alf Bjerckes vei

NMM 2045 Alf Bjerckes vei, Twin spirits, is a shiny, cryptocrystalline (CC) type with two large nickel-iron beads at the front, caused by spin during atmospheric entry. It is almost like two aerodynamic micrometeorites in one. Closer to the metal beads, the elongated matrix is lighter, drained of iron. This iconic stone (~300µm) is recognised by micrometeorite collectors worldwide from the full-page photograph in the Atlas of Micrometeorites (page 68). A historic opportunity to acquire.

 

PROVENANCE: The catalogue number refers to

the NMM archive, the index of Jon Larsen’s

Project Stardust collection, which is the  reference

collection for urban micrometeorites. The stone

was found,  curated, and selected by Larsen.

It is in pristine condition, fresh from  Space.
