Martian meteorite (basaltic shergottite)



Ten stones totaling 4012.43 g were found early 1999 in the sand desert of Dar al Gani. 
The biggest individual was a complete individual of 3090 g with perfect orientation and rather fresh appearance. 
Classification and mineralogy (A. Greshake and M. Kurz): an olivine-phyric shergottite with porphyritic texture; 
large chemically zoned olivine megacrysts are set into a fine-grained groundmass composed of pyroxene and maskelynite; 
minor phases include chromite, Ti-rich chromite, sulfides, phosphates, and small Fe-rich olivines; 
olivine megacrysts often contain melt inclusions and small chromites; pyroxenes are dominantly chemically zoned pigeonites, 
some contain orthopyroxene cores; olivine phenocrysts, Fa31.4-41.1, Fe/Mn = 52-59; matrix olivine, Fa37.4-40.6, Fe/Mn = 52-58; 
pigeonite, Fs23.7-35.4Wo6-18.6; orthopyroxene, Fs20.2-24.5Wo2.5-4.7, Fe/Mn = 34; maskelynite, An58.9-65.5; 
heavily shocked with numerous melt veins and melt pockets; moderately weathered with calcites filling cracks and cavities. 
Oxygen isotopes (R. Clayton and T. Mayeda, UChi): ?17O = +2.91, ?18O = +5.29, ?17O = +0.16. 
Possibly paired with Dar al Gani 467, 489, 670, 735, 876, and 975.
