Abstract
Present downslope iron accumulations were investigated in the rainforest
zone in southern Cameroon. Six clay and Fe-hydroxide dominated patterns
have been identified and occur on the lower part of hill slopes. They
can be subdivided in three different sequences, related to gentle,
moderate or steep slopes. They are discontinuous with respect to the
dismantling zone of the old ferricrete cap formed at Cretaceous period.
They show a gradual development from a soft Fe-crust (carapace) to a
vesicular facies that will, with time, cover the whole landscape again.
