Dalcher, N. Greber, B. Hofmann, S. Lorenzetti and F. Zurfluh. Physical characteristics: Elongated brown stone and smaller fragment without fusion crust, combined mass 266.2 g. Petrography: (B. Hofmann, NMBE, F. Zurfluh IFGBE, E. Gnos, MHNGE): The rock shows an equigranular texture with 0.5-2 mm grain size and consists of olivine with subordinate Ca-rich pyroxene (pigeonite). The px/(ol+px)-ratio is ~0.2. Common carbon-platelets (up to 0.2 × 2 mm), showing some parallel orientation, consist of graphite and diamond (2-10 μm in size). Accessory phases are Fe and troilite. Glass inclusions occur in reduced rims of olivine grains. The shock grade of silicates is S2. Geochemistry: Olivine Fa21.2 to nearly pure forsterite in reduced rims; pigeonite Fs17.9Wo10.1. Bulk analysis shows Fe/Mn (wt) = 47.7, Ni = 1380 ppm. Specimens: All at NMBE. | ||||||||||||||||||||||||||||||||||||
