NMM 2772 - Gardermoen

NMM 2772 Gardermoen is a cryptocrystalline (CC type) droplet with an intriguing glass tail. The large (~0.4mm) micrometeorite originally formed as a melted glass droplet, possibly due to spin during atmospheric entry, and features a substantial metal bead at the front. The nickel-iron bead prompted crystallisation in the melt, but inertia during deceleration pushed it out, leaving a crystal crater, as shown in one of the photos. Then, crystallisation continued backwards from the thick end, but solidification occurred before it was complete. Consequently, the droplet exhibits an intriguing glassy region on its tail. A museum-quality micrometeorite.

 

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.

VERIFICATION: The MM has been confirmed

extraterrestrial by visual identification and/or

SEM/EDS analysis by Jon Larsen. The stone is

mounted on a durable aluminium/glass/cardboard

microslide and is delivered together with a signed
