NWA 13227 is a Martian Shergottite found in Northwest Africa in 2019 and officially published in the Meteoritical Bulletin in 2020. More specifically, it is described as an Olivine-Gabbroic Shergottite, a relatively uncommon Martian lithology that differs from other Gabbroic Shergottites due to its higher olivine content. Like other Martian meteorites, NWA 13227 formed through igneous processes on Mars before being ejected from the planet by a powerful impact event and eventually reaching Earth.

NWA 13227 specimens often show a grey to greenish crystalline interior, reflecting their Martian mineralogy. Research describes the meteorite as containing oscillatory-zoned pyroxene and olivine set within a matrix of maskelynite, Fe-Cr-Ti oxides, phosphates, and sulfides. This texture points to an intrusive igneous history, where molten material cooled within the Martian crust rather than simply forming as a surface lava flow.

Studying NWA 13227 provides valuable insight into Martian magmatism, crustal evolution, and the relationship between different Shergottite types. Its Olivine-Gabbroic classification makes it especially interesting for understanding intrusive processes within the Martian interior. For collectors, NWA 13227 offers a recognised and visually distinctive Martian meteorite with strong scientific value. Each specimen represents genuine material from Mars, preserving part of the volcanic and intrusive history of the Red Planet.
