A sculptural beauty from Space.
Micrometeorite [NMM 2034] is an average sized (~0.25 millimeters) cryptocrystalline (CC) type micrometeorite with aerodynamic form. It has large olivine (forsterite) crystal domains in a “turtleback” variety. The color is lighter than normal, possibly due to extended oxidation during formation, possibly a clue to atmospheric entry angle and origin. In the front there is a large nickel-iron mound migrated to the front during the atmospheric deceleration. A few smaller magnetite crystals are visible on the surface in the SEM image. The stone was found 2019 0424 on the roof of Alf Bjerckes vei 26, Oslo, Norway.
NMM 2034 - Brobekk
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 fifth season of micrometeorite findings/verification in populated areas (2019). 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 a portfolio of one digital color photo, and one backscatter SEM image. Note the image credit for the micrometeorite SEM pictures: ©Jon Larsen (University of Oslo, UiO, Department of Geosciences), and the color photo: © Jan Braly Kihle/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.
