河北省物理地层界线厘定

以现代地层学多重划分为理论依据,以岩石地层单元组的密度、磁化率、剩余磁化强度及厚度加权算术平均值等物性参数为研究对象,以有序地质量最优分割方法为数学手段,进行河北省全区综合地层柱物理地层界线的厘定,并对其地质意义进行了初步讨论。

THE DEFINITION AND DETERMINATION OF PHYSICAL STRATIGRAPHIC BOUNDARIES IN HEBEI PROVINCE

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.
