Physical Description: Roberta Score Dull blistery fusion crust completely covers one surface and appears as patches on the other surfaces. Areas void of fusion crust have a pinkish tinge. Single mineral clasts as large as 5 mm in longest dimension are abundant as are gray veins (1-5 mm wide) which show higher relief than the surrounding material. A single green crystal and several reddish-brown minerals are present. Dimensions: 3 x 2.5 x 1.5 cm
Petrographic Description: Brian Mason The section shows angular clasts of pyroxene, up to 3 mm in greatest dimension, in a groundmass of comminuted pyroxene. The only other minerals noted were rare grains of plagioclase and trace amounts (less than 1%) of nickel-iron. Remnants of fusion crust are present along one edge. The section is stained brown with limonite. Microprobe analyses show the pyroxene of uniform composition, Wo2Fs24En74; it contains 0.47% A12O3, 0.64% MnO, and 0.07% TiO2. The meteorite is a diogenite. | ||||||||||||||||||||
