Showing the portions of FB-A1 highlighted as (i), (ii), (iii), and (iv) in Fig. 2a. a The (i) portion corresponding to the inner part of micrometeorite with rectangle enlarged in Fig. 5. b The (ii) portion corresponding to an enlarged particular of magnetite rim. c The (iii) portion of Al-Cu alloy. Ktk = khatyrkite, Slp = stolperite (note in stolperite the presence of lamellae with different scale of gray, corresponding to tiny brighter veins of Cu3Al2), (d) the (iv) portion with hzl: hezwooldite grain.
