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.
