Northwest Africa 7034 is a Martian meteorite believed to be the second oldest yet discovered. It is estimated to be two billion years old and contains the most water of any Martian meteorite found on Earth.
crystallization or other igneous process, NWA 7034 is a polymict breccia with clasts from several different and unrelated igneous sources. Udry et al. (2014) report an unusual, large, sub-rounded clast in NWA 7034 exhibiting a vitrophyric texture, with skeletal pyroxene and olivine with mesostasis (Figure 10).

Abstract. We report data on the martian meteorite Northwest Africa (NWA) 7034, which shares some petrologic and geochemical characteristics with known martian meteorites of the SNC (i.e., shergottite, nakhlite, and chassignite) group, but also has some unique characteristics that would exclude it from that group.

Feb 2, 2022 · Martian meteorite Northwest Africa (NWA) 7034 is a regolith breccia that contains remnants of the earliest Martian crust. The paucity of shock deformation in NWA 7034 was previously cited as recording a decline in giant impacts by 4.48 billion years and evidence for habitable Mars by 4.2 billion years ago.
