Writeup from MB 108:

Dar al Gani 1070 (DaG 1070)        27°01.01’N, 16°23.0’E

Al Jufrah, Libya

Find: August 1998

Classification: Ureilite

History: One stone with a total mass of 119.7 g, having remnant fusion crust with a few visible remaining flow-lines, was found by an anonymous finder in August 1998 in the Dar al Gani region, Libya.

Petrography: (A. Bischoff, IfP) The thin section is dominated by medium to coarse-grained anhedral grains of olivine and pyroxene showing grain contacts with abundant 120° triple junctions. Olivine is by far the most abundant silicate, while pyroxene is quite rare. Olivines have thin reduction rims and abundant terrestrial oxides are in the boundary areas. Graphite is present. The sample is strongly weathered.

Geochemistry: Mineral comopositions and geochemistry: (K. Klemm; A. Bischoff, IfP) : Olivine cores are Fa17.7-20.0 (n=4) and the reduced rims have low FeO (down to Fa3.2). Low-Ca pyroxene has a composition of Fs17.2±0.3Wo6.4±0.2, n=3).

Classification: Ureilite based on mineralogy, texture, and mineral chemistry.
