Discovery of new Al-Cu-Fe minerals in the Khatyrka CV3 meteorite
Introduction: During a nanomineralogy investigation of the Khatyrka CV3 carbonaceous chondrite, we have identified two new alloy minerals (AlCu with a Pm-3m CsCl structure and Al_3Fe with a C2/m structure) and associated icosahedrite (quasicrystal Al_(63)Cu_(26)Fe_(11) with a five-fold symmetry) at...
