A classical porphyritic olivine (PO)
Micrometeorite [NMM 2577] is a small (~0.2 millimeters) classical porphyritic olivine (PO) type micrometeorite. It is black and has large well shaped olivine (forsterite) crystals in abundant glass, which means this stone is fresh from Space. Some areas display an interesting “skeletal” crystallization with inwards growth. The electron microscope image reveals magnetite crystals on the surface. The stone was found 2020 0801 at Nesodden, Viken, Norway.
NMM 2577 - Nesodden
Top quality micrometeorite mounted on a signed microslide (cardboard/aluminum/glass). The stone is from Jon Larsen’s collection and is in pristine condition (no sign of weathering, low terrestrial age), complete and oriented.
The stone is a part of the collection found during the sixth season of micrometeorite findings/verification in populated areas (2020). The catalog 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.
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, a signed label, plus one image from the electron microscope. Note the image credit: © Jon Larsen/Project Stardust. Upon delivery, before opening the glass, please check under the microscope if the stone has loosened from the center of the tape inside the microslide during transportation. If dislocated, it can easily be moved with a damp toothpick or pointed wooden stick.
