[5] It was originally described as a volcanic breccia that has a porphyritic appearance, consisting of plagioclase (andesine) and pyroxene (pigeonite and augite) phenocrysts that are up to 5 mm in diameter set in a fine grained groundmass.

[2] NWA 7034 was classified as an ungrouped planetary achondrite until the Meteoritical Society approved the new designation "Martian (basaltic breccia)" in January 2013.

[2] In 2018 the Nomenclature Committee of the Meteoritical Society accepted a petition to reclassify the NWA 7034 pairing group as "Martian (polymict breccia)".

A 2022 study concluded that meteorite NWA 7034 was ejected from Mars by the impact that formed the crater Karratha about 5-10 million years ago in the Terra Cimmeria-Terra Sirenum region of the southern highlands.

The authors proposed that before its ejection, this meteorite was part of the ejecta deposits from an earlier impact that formed the nearby Khujirt crater approximately 1.5 billion years ago.
