An ultrarare micrometeorite.
A unique micrometeorite! [NMM 707] is a large (~0.3 millimeters) porphyritic olivine (PO) type, with irregular but slightly aerodynamic form. It has large olivine crystals in abundant dark chondritic glass. The surface is sprinkled with octahedral magnetite crystals. The stone has several rare nickel oxide chunks and rosettes (crystalline nickel oxide) on the surface, one with an ultrarare globular nickel sulfide core in the center. The stone was found 2016 0902 on the roof of Forskerfabrikken, Oslo, Norway.
NMM 707 - Forskerfabrikken
Top quality micrometeorite mounted on a signed microslide (cardboard/aluminium/glass). The stone is purchased from Jon Larsen via Treasures From Space. The stone is in pristine condition (no weathering, low terrestrial age), complete and oriented.
The stone is a part of the collection found during the second season of micrometeorite findings/verification in populated areas (2016). The catalogue number refers to the NMM archive (the main index of Norwegian Micro Meteorites, Jon Larsen’s urban Stardust Collection), and the stone was found and curated by Jon Larsen during the work with the Atlas of Micrometeorites.
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 sold with this Certificate of Authenticity incl. classification, a signed label, plus a portfolio of one digital color photo, and two backscatter SEM images.
