Dar al Gani 735          27\27210'N, 16\260 10' E
   Found 1996/97 winter
   Martian basalt (shergottite)
A 588 g complete stone covered with desert varnish was collected
in the Dar al Gani region.  Classification and mineralogy (F. Wlotzka,
MPI; M. Kurz, Neukirchen, Germany):  a porphyritic basalt with
mm-sized olivines (normally zoned from Fa28 to Fa37) in a finer
grained matrix of pigeonite (Fs25-28) and feldspathic glass (An65);
a direct comparison with a thin section of DaG 476 shows that both
stones are very similar and are probably paired; however, DaG 735
does not contain terrestrial carbonate veins, and appears less
weathered than DaG 476.  Specimens: type specimen, 6 g, MPI; main
mass with anonymous finder.
