Writeup from MB 98:
Dar al Gani 1051 (DaG 1051) 27°10.15’N, 16°08.12’E Libya Found: 2000 Classification: Martian meteorite (shergottite) History: A stone was found in the strewn field of Dar al Gani 476. Physical characteristics: One stone of 40.1g with a partly brownish surface was recovered. Petrography: Classification and mineralogy (A.Bischoff and M. Horstmann, IfP, and Erich H. Haiderer, Vienna, Austria): The rock is slightly weathered and has a porphyritic basaltic texture consisting of large, up to mm-sized zoned olivines embedded in a fine-grained matrix of pyroxene and maskelynite (the plagioclase has been converted to maskelynite). Minor mineral constituents include Fe-sulfide, chromite, Ti-rich chromite, and ilmenite. Based on the optical appearance the rock is similar to Dar al Gani 476 and very probably paired. Geochemistry: Maskelynite (plagioclase), An47-64 ; mean: An55.5±6; pyroxene, Fs19-33; mean: Fs26±4.5; olivine (range): Fa26-45. Classification: The rock is a Martian shergottite and probably paired with Dar al Gani 476 and other samples found within this strewn field. Specimens: Type specimen of 8.4 g and one polished thin section prepared from this mass, IfP; the finder (anonymous) holds the main mass. | ||||||||||||||||||||||||||||
