Abar al’ Uj 014 (AaU 014) 22°26.380’N, 48°52.250’E Ash Sharqiyah, Saudi Arabia Found: 31 Jan 2012 Classification: Carbonaceous chondrite (CO3) History: Found by Edwin Gnos, Beda Hofmann, Khalid al Wagdani, Ayman Majoub, Abdulaziz Solami, Siddiq Habibullah, Maruan Al Bokari during a search for meteorites on Jan. 31, 2012. Physical characteristics: Dark brown, wind-ablated, partially broken 429.4 g individual, no preserved fusion crust. Petrography: (E. Gnos, MHNGE and B. Hofmann, NMBE) Abundant chondrules (approx. 60% vol), matrix approx. 40% vol. CAIs up to 500 μm. Chondrule size averages 0.28±0.14 mm (n= 180, maximum size 0.90 mm). Chondrules commonly contain brown glass. Abundant troilite and iron metal (approx. 5:1). Shock grade S1. Weathering: about 50% of metal is oxidized. Geochemistry: Olivine compositions are Fa0.5-56.5, median Fa35.5 (n=72), pyroxene compositions are Fs0.0-22.1Wo0.5-6.2, median Fs2.6Wo1.4 (n=19). Oxygen isotopes: (R. Greenwood, OU) gave δ18O = -0.14, δ17O = -4.59, Δ17O = -4.52 (all permil) Classification: Based on Chondrule size, matrix abundance and geochemistry this is a CO3 chondrite. Specimens: Type material (21.70 g) and three polished thin sections at MHNGE, main mass at SGS. | ||||||||||||||||||||||||||||||||||||||
