High-angle annular diffraction-scanning transmission electron microscope (HAADF-STEM) images of the severely heated micrometeorites (MMs.) a Euhedral magnetite crystals (Mt) and interstitial glass (Gl) near the original surface of D03IB057. Dendritic magnetite (Dendritic mt) overgrowth on the surface of the euhedral magnetite crystals. b Olivine in D10IB170 contains abundant patches composed of magnetite and glass. The inset shows an enlarged HAADF-STEM image of a magnetite–glass (Gl) patch
