Dar al Gani 1055 (DaG 1055) 27°22.80’N, 16°28.14’E Al Jufrah, Libya Found: 2007 Classification: HED achondrite (Eucrite, polymict) History: A single 305 g stone was found in 2007 by Romano Serra. Physical characteristics: The main mass has a small portion of a black fusion crust. Petrography: (V.Moggi Cecchi, G.Pratesi, S.Caporali, MSP) Polymict breccia of fine- and coarse-grained regions. The coarse-grained areas consist of plagioclase and clinopyroxene crystals to 1.6 mm. Fine-grained regions show clino- and orthopyroxene clasts set in fine-grained matrix of unexsolved Fe-rich pigeonite, exsolved pigeonite (orthopyroxene with augite lamellae) and maskelynitized calcic plagioclase. Minor phases include ilmenite and Al-Ti-chromite. Exsolved pyroxene grains show alternating fine low-Ca pyroxene and augite lamellae (2 to 9 μm). Geochemistry: Maskelynite An78.7-88.5Or0.47-1.46; Low-Ca pyroxene Fs32.3-37.7En53.2-59.5Wo2.8-14.5 (Fe/Mn=26.8-33); Augite lamellae Fs35.7-44-7En28.4-30-9Wo24.5-35.9 (Fe/Mn=30.4-35.7); unexsolved pigeonite, Fs55.3-59.8En32.1-34.6Wo5.6-12.6 (Fe/Mn=32.2-35.9). Classification: Achondrite (eucrite, polymict) with high degree of shock and low degree of weathering. Specimens: A total of 60 g specimen and one thin section are on deposit at MSP (MSP 5104). OAM holds the main mass. | ||||||||||||||||||||||||||||||||||
