Dar Al Gani 735 Location 27° 10'N, 16° 10'E
Libya
Find 1997
Martian meteorite (basaltic 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 millimeter-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. |
