Glauconite sandstones with gravel, silt and mica-containing clay from the Paleogene dominate the upper reaches . In the estuary, loess and sand loess occur with silty to fine sand rocks from the Pleistocene .
The rock is covered by Pararendzina soils in the source area and on the upper course, as well as parabroun earths on the lower course and in the mouth area.
