Pontian and Dacian formations in the eastern area of the Dacian Basin are represented by a succession of poorly consolidated clay, sand and sandstones, formed in dulcicol, low deep environment. This is evidenced by the existence in these rocks of characteristic fossils for this type of environment. In gray clay rocks sometimes black charcoal clay enclaves are found. Some alternate layers of metric thick layers of clay, sandy clay and clayey sands with charcoal intervals of thickness from a few centimeters to almost a meter can be found here. The total thickness of this succession, ranging between Romanian and Pontian, reaches up to 750 m. Most of these rocks are poorly consolidated, and have a fairly low content of minerals with higher densities and important magnetic properties. Below there is a layer of salt from several tens of meters up to 200 m (in the Manzalesti area). From a gravimetric and magnetic point of view, these formations generate negative anomalies, their densities being below 2.5 g / cm3, and magnetic susceptibilities vary between 15 and 250 * 10-6 USI. The charcoal deposits in these rocks are of no particular economic importance because they have low thicknesses and are unprofitable for exploitation, but can be used as a reference for the correlation of sedimentation processes across the Dacian Basin.
