| Abstract | Introduction: Northeast Africa 001 (NEA 001) is a 262 g lunar meteorite found in 2002 in northern Sudan. This rock is a clast-rich anorthositic regolith breccia with minor mare basalt component. Petrography: NEA 001 is a polymict regolith breccia composed of various types of lithic clasts (up to 1 cm in size), isolated mineral fragments, glass fragments and spherules embedded in a wellconsolidated microcrystalline impact melt matrix (Fig. 1). The rock is heavily fractured as a result of multiple shock events, but it remains coherent due to the presence of impact-melt matrix. Typical composition of the impact-melt matrix is (wt%): SiO2 = 45.7, Al2O3 = 24.1, FeO = 7.2, MgO = 7.4, CaO = 14.6, Na2O = 0.5, TiO2 = 0.5. |
