A little Space rock with a dramatic formation!
The life story of micrometeorite [NMM 3719] is described in the Project Stardust blog: https://www.facebook.com/photo?fbid=592510059562534&set=a.414001680746707
The fascinating rarity is a glassy (V-type, vitreous) micrometeorite with a nickel-iron bead in the front and a huge open gas vesicle from degassing of volatiles in the back. At the lower part are two smaller extremely shiny (pure nickel?) secondary/tertiary metal beads, the largest of the two surrounded by a narrow crystalline rim. In the thicker part of the glass, near the front is a still sealed gas vesicle. A raman spectroscopic analysis may reveal which volatile elements are trapped inside.
The stone was found September 9, 2022, at Vallhalla Sports Arena, Oslo, Norway. Where Werner Herzog filmed his stardust hunt in the movie “Fireball” two years earlier.
NMM 3719 - Vallhall
Top quality micrometeorite mounted on a signed microslide (cardboard/aluminum/glass). The stone is from Jon Larsen’s own collection and is in pristine condition (no sign of weathering, low terrestrial age), complete and oriented.
The catalogue number refers to his index, the NMM archive (the main index of Norwegian Micro Meteorites, Jon Larsen’s urban Stardust Collection). The stone was found and curated by Jon Larsen.
VERIFICATION: The MM has been confirmed extraterrestrial by SEM/EDS analysis and visual identification by Jon Larsen, and is a verified micrometeorite, hereby confirmed in writing. The stone is delivered with a signed Certificate of Authenticity incl. classification, and one digital color photo by Jan Braly Kihle and Jon Larsen.
