Paragenetic relationship between ferromanganese and calcareous nodules in a hydromorphic toposequence

Abstract

Although both ferromanganese and calcareous nodules are common in hydromorphic soils, their joint presence has rarely been evaluated. Studying their occurrence in soils forming toposequences may significantly contribute to a better understanding of their formation. We investigated the relationship between their formations in four soil profiles from a salt affected toposequence through mineralogical, micro-fabric, micro-chemical, morphological, and stable isotope analyses.
