La météorite achondrite la plus rare Non groupée NWA 7325 Probablement de la planète MERCURE !!! - 0.07 g - (1)
Classification: Ungrouped achondrite
Physical characteristics: A group of essentially identical dark green, uncrusted stones ranging in size from 99 g to g. Distinctive green clinopyroxene and gray, frosty plagioclase are evident.
Petrography: (A. Irving and S. Kuehner, UWS) Cumulate igneous texture. Composed mainly of calcic plagioclase, diopside and forsterite with accessory Cr-bearing troilite and kamacite. Lobate forsterite grains are commonly associated with elongate pores.
Geochemistry: Olivine (Fa4.5-4.6, FeO/MnO = 36-41, N = 3), clinopyroxene (Fs1.8-2.2Wo44.3-43.8, FeO/MnO = 12-15, N = 3).
Classification: Achondrite (ungrouped). Paired with NWA 7325, NWA 8014 and other stones from the Bir Abbas site.
