Abstract—Analysis of the paleohydrodynamic characteristics of sedimentation environments allowed us to reconstruct formation conditions of the Cambrian–Ordovician sandstone sequence (COS) in the Leningrad district. Reconstruction of the paleolithodynamic parameters showed that the real timing of the sequence (sedimentation duration) is considerably less than the related stratigraphic scale interval. Such a situation is also encountered in other sedimentary formations. Determination of the real sedimentation rate can affect the assessment of mineral resources in a sedimentation basin.
