Results are presented on SEM and optical microscopy investigations and on microprobe analyses of a fragment of the Kaidun III (EH5) meteorite. The results show that the material collected from the border region of the fragment underwent heavy hydrothermal alterations by hot fluids formed during the last accumulation impact in the meteorite's history, accompanied by an intensive migration of all the main components. The fluids in the meteorite changed with time from weakly acidic (pH below 6.5) at the beginning to alkaline (pH about 10), with temperatures higher than those estimated for CM chondrites during their alteration. By the action of these fluids, metallic Fe transformed to PCP (poorly characterized phases) material, whereas schreibersite transformed to a mixture of Ni disulfide and Fe oxides.
