(Table 1) Rock magnetic parameters of core samples obtained from Morne Rouge, Ile de Possession

The magnetic high field susceptibility chi(hifi) indicates the presence of mafic paramagnetic minerals in the scoriae and points to an absence of clay minerals, and in turn of pedogenic processes, in the peat samples. Due to their volcanic origin, scoriae contain much more ferrimagnetic minerals than peat with is indicated by their enhanced saturation remanence Mrs.
