Writeup from MB 102:

Dar al Gani 1046 (DaG 1046)        27°24’10"N, 16°18’20"E

Al Jufrah, Libya

Found: 2005 Sep

Classification: HED achondrite (Eucrite, monomict)

Physical characteristics: Weathered brown stone.

Petrography: (C. Cordier and L. Folco, MNA-SI) Breccia consisting of lithic clasts set in a fine-grained clastic matrix. Clast size is up to 1 cm. Lithic clasts are dominated by basaltic eucrite. They are composed of exsolved pyroxene (pigeonite and minorly augite) and lath-shaped bytownite with sub-ophitic texture. Accessory phases include chromite, ilmenite, silica, zircon. Different clasts have variable grain size, ranging from 100 to 700 μm. Some of the smallest clasts consists of blocky low-Ca pyroxene showing compositional normal zoning.

Geochemistry: Bulk Fe/Mn = 30.4 by FPXRF. Mineral chemistry: Pigeonite Fs55.5±3Wo6.8±3.3 Fe/Mn=22.9±2.3 (n=16), augite Fs25.9±0.2 Wo41.0±0.1 Fe/Mn=25.4±4.2 (n=2), bytownite An87.2±2.8 (n=6).

Classification: Polymict eucrite breccia
