Writeup from MB 100:

Dar al Gani 1053 (DaG 1053)        27°14.50’N, 16°13.96’E

Al Jufrah, Libya

Found: 2006

Classification: Carbonaceous chondrite (CV3)

History: Two small stones weighing 98 g were found by Mario Riva.

Physical characteristics: The main mass has no fusion crust. A cut surface on the type specimen shows rather large chondrules and some small white spots.

Petrography: V. Moggi Cecchi, G. Pratesi, S. Caporali, MSP. Thin sections show an abundance (40 vol. %) of well-defined chondrules (PO, GO and poikilitic POP) set in a dark brown matrix. Chondrules are typically 350 to 750 (mean 500) μm in diameter. Chondrules contain variable amounts of clear glass. Fe,Ni alloy (mainly tetrataenite with Fe 50.4, Ni 48.4, and Co 1.2 wt.%) and troilite are uncommon (less than 5 vol. %). Rare apatite grains are present. CAIs are visible on the cut surface of the type specimen.

Geochemistry: Olivine in both chondrules and matrix is Fo-rich (Fo97.4-99.4, mean Fo98.5). Low-Ca pyroxene is enstatitic with a variable composition (En82.7-98.5Fs16.5-0.7Wo1.0). An augitic pyroxene with variable composition is also present (Fs1.6-2.4En62.0-56.8Wo36.4-40.8, Al2O3=3.4-3.5 wt.%); Oxygen isotopes: (I.Franchi, R.Greenwood, OU) δ17O = -4.537, δ18O = -0.320, Δ17O = -4.371 per mil.

Classification: Carbonaceous chondrite (CV3); minor weathering

Specimens: A total of 28 g and one thin section are on deposit at MSP (MSP 5105). OAM holds the main mass.
