The morphology and composition of manganese oxide accumulations associated with the structural pores in a black earth (Typic Pellustert) subsoil layer were examined using light microscopy, electron microscopy, X-ray diffraction and electron micro-analytical techniques. Birnessite was identified as the crystalline manganese oxide phase. There were significant positive correlations between Co, Ca and Mn and a significant negative correlation between Fe and Mn. It was most probable that both microbial oxidation and auto-oxidation of Mn contributed to the formation of the manganese oxide accumulations in this soil.
