Diogenite (Brecciated)

The section is a breccia composed of fragments of orthopyroxene (up to 3.5 mm) and minor plagioclase, oxide minerals, troilite, Fe-metal. There are several lithic clasts composed of fine-grained troilite and silicate minerals. Compositions of low-Ca pyroxene are Fs23.0-31.5, and wt. FeO/MnO = ~30. Plagioclase compositions are An82.9-92.8.
