Black fusion crust that is rough in some areas and shiny in others covers 90% of the exterior. There is one shiny, smooth brown spot that is about 3 mm in size. Exposed interior is light gray matrix with inclusions that range in color from white, to dark gray to black. Fresh interior is a light gray matrix with dark gray and white inclusions and a few very small spots of orange rust, a couple of light grayish-brown inclusions and some dark gray-black reflective mineral grains. |
This section consists of a medium grained, ophitic basaltic texture of pyroxene and plagioclase cross cut by shock veins. Many pyroxene grains show mosaicism, particularly in association with shock veins. Pyroxenes are Fs40-60Wo5-30 and feldspars are An66-90Or0.3-4. The meteorite is a eucrite. |
