  abstract = {{T}he aim of this study was to characterize carbon sequestration by mineralogical control at the scale of a volcanic soil horizon. {W}e adapted the classical density fractionation procedure and focused on the heavy fractions (> 1.9), which we divided into eight organomineral fractions. {W}e characterized them simultaneously through non-destructive mineralogical analyses ({XRD} and {NMR} of {A}l and {S}i) and organic carbon analyses. {T}he results showed that the largest proportion (82.6%) of organic matter in the horizon was associated with minerals in organomineral complexes. {I}mogolite type materials bound 6-fold more {OM} than anorthoclase, and 3.5-fold more {OM} than iron oxides. {I}n addition, we observed a degree of polymerization of imogolite type materials that was midway between that of allophane and {A}l in {A}l-humus complexes. {I}n conclusion, the results of this density fractionation combined with a mineralogical approach suggested that {OM} in the heavy fractions could be divided into several pools depending on the nature of the minerals.},
