Dhofar 1675 (Dho 1675) 18°15.54’N, 54°1.768’E Zufar, Oman Found: 2004 Classification: HED achondrite (Eucrite, polymict) Physical characteristics: A greenish-brown stone lacking fusion crust was found in 2004 on the desert plain in the Dhofar region. Petrography: (Ansgar Greshake, MNB) The meteorite is dominated by large Ca-rich feldspar (maskelynite) and brownish pyroxene typically showing fine exsolution lamellae. Minor phases are chromite and silica polymorph. Constituent mineral phases display strong shock effects, e.g. feldspar is converted into maskelynite and pyroxene shows undulatory extinction and intense twinning. Shock veins and melt fragments are found throughout the specimen. The meteorite also contains small clasts with basaltic texture. The meteorite has a low degree of weathering. Geochemistry: Ca-rich pyroxene is Fs22.4-26.1Wo41.1-45.1, FeO/MnO=31; Ca-poor pyroxene Fs54.7-57.8Wo1.8-3.4, FeO/MnO=32; plagioclase is An 82.9-91.2. Classification: HED achondrite (eucrite-pmict) | ||||||||||||||||||||||||||||
