Writeup from MB 101:
Dar al Gani 1058 (DaG 1058) 27.375°N, 16.184°E
Al Jufrah, Libya
Found: 1998 Sep 9
Classification: Lunar meteorite (feldspathic breccia)
History: A fairly large stone was found in 1998 September on the Dar al Gani plateau, Libya, near the find site of Dar al Gani 400.
Physical characteristics: Compact, fine grained gray stone (1815 g) with visible whitish to pale gray clasts and partially coated by orange-brown weathering products.
Petrography: (A. Irving and S. Kuehner, UWS) Very fine grained melt matrix breccia with larger feldspathic clasts. Minerals are anorthite, olivine, low-Ca pyroxene, more calcic pigeonite, Ti-bearing chromite, ilmenite and troilite.
Geochemistry: Olivine (Fa16.0-33.9; FeO/MnO = 90-108), low-Ca pyroxene (Fs29.8-30.3Wo4.8-6.4, FeO/MnO = 50-57), pigeonite (Fs33.7Wo10.2; Fs43.6Wo7.3; FeO/MnO = 59-61). Bulk composition (R. Korotev, WUSL): mean values from INAA of subsamples are 3.0 wt.% FeO, 5.1 ppm Sc, 80 ppm Ni, 1.4 ppm La, 0.6 ppm Sm, 0.69 ppm Eu, 0.48 ppm Yb, 0.2 ppm Th.
Classification: Lunar (feldspathic breccia). This specimen was found close to Dar al Gani 400, and similarities in mineralogy and bulk composition indicate that these are likely paired.
Specimens: A total of 25 g of type material is on deposit at UWS. The remainder is held by an anonymous collector.
