Some of these stones are of meteoritic and others of terrestrial origin. Physical characteristics: 35.2 g dark gray-brown irregular angular stone with pitted surface Petrography: (R. Bartoschewitz, Bart) well developed chondrules (0.1-1.2 mm, av. 0.5 mm) of various types set in a fine-grained brown matrix. Metallic phases are almost completely weathered. Geochemistry: (R. Bartoschewitz, Bart, P. Appel and B. Mader, Kiel) Olivine Fa17.4 (8.6-17.4; Fe/Mn=42-56, av. 40; n=26); poor Ca pyroxene Fs6.4 (4.6-10.7) Wo3.9 (3.4-4.8); Fe/Mn=22-28; n=4). Kamacite Ni=6.2, Co=0.6 wt% (n=1). Magnetic susceptibility (R. Bartoschewitz, Bart): log χ (× 10-9 m3/kg) = 4.85. Classification: Ordinary chondrite (H3, S1, W4) Specimens: 8.5 g on deposit at Kiel, 21 g and polished thin section with Bart | ||||||||||||||||||||||||||||||||||||
