Porphyritic olivine (PO) from the Atlas of Micrometeorites.
Micrometeorite NMM 1172 is an average sized (~0.25 millimeters) porphyritic olivine (PO) type stone with an irregular but aerodynamic form. It has large olivine crystals in abundant olive chondritic glass. In the front there is a large nickel-iron mound, and a secondary smaller bead at the rare end, due to spin during atmospheric entry. A few smaller magnetite crystals are visible on the surface in the SEM image. The stone was found 2018 0422 in the rain gutter of Jon Larsen’s house in Brevik, Viken, Norway – where the World’s very first urban micrometeorite had been found three years earlier.
