Description from Meteoritical Bulletin No. 83: A brownish stone weighing 2015 g was found in Dar al Gani, Sahara.  Mineralogy and classification (J. Zipfel and P. Scherer, MPI):  fusion crust absent; meteorite has a porphyritic texture, consisting of olivine embedded in a fine-grained matrix of clinopyroxene laths (pigeonite and minor augite) and interstitial feldspathic glass; mineral abundances similar to EET 79001 lithology A; Fe-sulfide, Ti-rich chromites, ilmenite and chromite present; shock features include twinning and fracturing of clinopyroxene, mosaicism of some olivine, and plagioclase converted to feldspathic glass; impact-melt pockets abundant; extensive terrestrial weathering resulted in carbonate veins crosscutting the meteorite along grain boundaries and cracks; bulk chemistry intermediate between basaltic and lherzolitic shergottites, with a high bulk Mg/(Mg + Fe), high con-cen-trations of siderophile elements, relatively low abundances of heavy rare earth elements (HREE), and a strong light rare earth element (LREE) depletion; exposure age 1.1 ± 0.2 Ma; 36Ar/132Xe and 84Kr/132Xe typical of Martian meteorites, and 129Xe/132Xe similar to Chassigny.  Oxygen isotopes (I. Franchi, OU):  d18O = 4.57, d17O = 2.69 permil rel.  SMOW (D17O = 0.317).  The petrography, mineralogy, and noble gas chemistry of DaG 476 and DaG 489 are very similar, and the two are likely paired (L. Folco, MNA-SI, and J. Zipfel and L. Schultz, MPI).  Specimens:  type specimen, several grams, and one polished section, MPI; main mass with anonymous finder.
