Smectites separated from three soils of Ganges Floodplain, Bangladesh, were characterized. The smectites content in the fine clay fractions was in a range of 62 and 88%. Expansion to 1.8 nm by the Greene-Kelly test and the (060) spacing around 0.150 nm suggested that the smectites were mainly beidellite-type. Elemental composition calculated from total chemical analysis showed that the smectites had layer-charge of tetrahedral-origin and were rich in Fe. The structural formula for the smectites of Silty Ganges Alluvium, which is hardly subjected to decalcification, was estimated as (Si_<6.90> Al_<1.10>) (Al_<2.46> Fe_<0.99> Mg_<0.76>)O_<20>(OH)_4 X_<1.25>. The impact of iron-rich beidellite on the soil fertility potential was discussed.
