Classification: Achondrite, Eucrite, polymict breccia
Place/Time: 04.2010 in Morocco
Fresh fragmental breccia composed mostly of cumulate eucrite mineral debris with some polymineralic cumulate eucrite and basaltic eucrite clasts, plus sparse diogenite clasts.
Geochemistry: Exsolved pigeonite (lamellae of clinopyroxene within host orthopyroxene), silica, calcic plagioclase, minor fayalitic olivine (Fa84.7-87.1), ilmenite and troilite. In most pigeonite grains the clinopyroxene lamellae are Fs11.5-12.2Wo45.2-44.7 (FeO/MnO = 19.8-24.4) and host orthopyroxene is Fs33.3-33.5Wo1.6-2.2 (FeO/MnO = 27.4-29.3), but in some more ferroan matrix grains the clinopyroxene lamellae are Fs29.0Wo42.3 (FeO/MnO = 32.4) and host orthopyroxene is Fs61.4Wo3.9 (FeO/MnO = 32.1). Orthopyroxene in diogenite clasts is Fs29.4-31.7Wo2.8-4.0 (FeO/MnO = 27.7-28.0).
