Found in Morocco in October 2019. Petrography: (K. Metzler, IfP) Achondritic breccia, consisting of mm-sized eucritic lithic clasts with ophitic to subophitic textures and monomineralic fragments (pyroxene, plagioclase) set in a fine-grained clastic matrix of related debris. Low-Ca pyroxene shows augite exsolution lamellae. Accessories are a silica polymorph, ilmenite, chromite, troilite, and some Ni-free metal.
