| Outline of Final Research Achievements |
The nature of submicron aggregate separated from an allophanic Andisol was studied using scanning transmission X-ray microscopy (STXM) and near-edge X-ray absorption fine structure (NEXAFS) as well as electron microscopy (SEM, TEM). The results of this study provided the direct evidence of preferential binding of microbially-altered C with poorly-crystalline mineral phases at submicron scale.
