Abstract With modern multiple stratigraphic classification as the theoretical basis, the density, susceptibility and residual magnetization of regional lithostratigraphic formations as the research objects, and the Fisher grouping for maximum homogeneity as the mathematical means, the authors defined and determined physical stratigraphic boundaries of the stratigraphic column in Hebei Province. Their geological implications have been discussed, which include crustal evolution, biotic succession, lithosphere dynamics, crust-mantle differentiation, lithofacies distribution etc.
