Dar al Gani 983

Libya

Found 2002 March 23

Achondrite (eucrite, polymict)

A single stone of 933 g, partially covered with a shiny black fusion crust, was found on the Dar al Gani plateau during a German-Libyan expedition by J. Schlüter, F. Thiedig, L. Schultz and Abd Elfatah M. Abu Agreb. Mineralogy and classification (J. Schlüter, Hamburg). The cut stone shows a bright grey surface with strong brecciation with open cracks and some melt veins with vesicles. Cracks and vesicles occasionally contain white aggregates of gypsum microcrystals. The meteorite consists of mineral and lithic clasts set in a fine-grained fragmental matrix. Clasts include: 1) megacrysts of pigeonite, Fs37.9Wo4.4 (range Fs31.1–51.1; Wo1.5–7.2), and plagioclase An94.8 (range An92.7–95.4) up to 10 mm in size; 2) equigranular, pigeonite, and plagioclase-bearing cumulate eucrite; pigeonite, Fs54.6Wo3.1 (range Fs48.5– 56.7; Wo1.5–9.8), with augitic (Fs25.0Wo40.9)) exsolution lamellae up to 7 micrometers wide and maskelinitized plagioclase, An93.6 (range An88.7–96.4) are present in equal proportions; 3) dark, recrystallized impact melt with a spinifex-like texture consisting mainly of pigeonite, Fs55.3Wo2.13 (range Fs54.1–56.4; Wo1.6–3.1) and plagioclase, An84.3 (An75.5–90.6). Diogenitic components have not been found. The opaque components show only slight weathering. Accessory minerals including ilmenite, chromite and troilite have been observed. The bulk composition of the meteorite is similar to Sioux County or Juvinas. Specimens: type specimens 281 g, Hamburg, 20 g, MPI, main mass, Industrial Research Center (IRC), Tripoli, Libya
