| Therefore, the ferruginization of the basal channel conglomerates is seen as coeval with ground-water ferricrete formation in the interfluves. |
| On the interfluves of incised valleys, sequence boundaries are marked by palaeosols that locally have a distinctive leached, potassium-depleted character. |
| It's situated in the centre of the European part of Russia, in the interfluves of the Oka and Volga rivers. |
| No information is available so far on the occupation or the exploitation of valleys and interfluves. |
| The basal conglomerates and the equivalent sands and muds on the interfluves are commonly ferruginized. |
| The saline crust is well developed on the interfluves between the valleys and shows little or no evidence for active runoff. |
