   Found 1999
   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
