  Martian meteorite (basaltic shergottite)
A 107.7 g olive-brown coloured stone of relatively angular shape with 
one small area of thin black-brown fusion crust was recovered on a 
Miocene fresh-water limestone gravel plateau about 43 km south of Al 
Ghaba by Rainer and Sven Bartoschewitz. Mineralogy and classification 
(R. Bartoschewitz, Bart): porphyritic texture with olivine 
phenocrysts up to 2 mm (Fo67-64) set in a matrix consisting of 
feldspathic glass (An53-66Or0.3-0.8) and pigeonite (En62-69Wo7-11) 
with minor Ca-poor pyroxene (En65-66Fs34-35). Shock melt veins and 
pockets are partly recrystallized. Shock stage S5. Oxygen isotopic 
composition (R.N. Clayton, UChi): d17O = +2.78 permil, d18O = +4.74 
permil, they fall in the SNC field. Analysed by P. Appel and B. Mader 
(Kiel). SaU 005, 008, 051, 060 and 094 were found in the same area
