The exterior is 25% covered in black, patchy fusion crust. The exposed interior has an overall greenish color. The matrix is gray and beige with some white clasts. The surface is heavily pitted with a cave-like structure in the center of the sample. Some green crystals are visible to the naked eye. The fresh interior shows a fine-grained beige, gray and white matrix. Some green crystals are visible. |
This meteorite consists of small (~200 micron average) fragments of basaltic material which occur as both the host and clasts within the meteorite. Occasional coarser grains and clasts (with sizes up to 0.5 mm) are observed. Mineral compositions are homogeneous with orthopyroxene (Fs30Wo2), with lamellae of augite (Fs12Wo44), and plagioclase (An92Or0.5). The Fe/Mn ratio of the pyroxene is ~29. Orthopyroxene is the dominant modal phase, which makes this meteorite a diogenite. |
