STEM-EDS-HAADF: Martian Meteorite NWA7533 sample. Detail of the composition and atomic structure of a titanomagnetite. A, B) EDS mapping of a TiO2 lamellae within the magnetite. Nanodomains of Fe/Cr composition can also be seen. The 2 nm thick interface is enriched in Cr. C) High-resolution HAADF image of TiO2 lamellae. D) High resolution HAADF image of Ti-rich bi-lamella within magnetite. Hugues Leroux (MTP-UMET), Maya Marinova (PMEL)

HAADF: An image of a primitive meteorite as old as our solar system showing the presence of diverse phases such as amorphous silicate, pyroxene, olivine, iron oxide, and organics. Corentin Le Guillou (MTP-UMET), Hugues Leroux (MTP-UMET), Adrian Brearley.
