| Abstract | Introduction: Research on Martian meteorites has led to the recognition of several shergottite subgroups, namely the relatively evolved basaltic shergottites, the lherzolitic shergottites, and the more primitive olivine-phyric shergottites. NWA 1195 had been classified as an olivine-phyric shergottite [1], but the discovery in 2003 of the 30 known Martian meteorite near Lakhbi, Algeria (provisional number NWA 2046) has led to the realization that both of these Mg-rich samples (containing preferentially aligned, prismatic phenocrysts of orthopyroxene in addition to olivine) properly belong to a separate shergottite subgroup. |
