| 摘 要： | 以河北省区域岩石地层组种元素含量为对象,以有序地质量最优分割方法为手段,进行化学地层界线划分.同时对地球化学异常层进行了梳理搜索,并对区域地层进行了地球化学对比,从而建立起区域地球化学格架.这是地层多重划分对比的重要组成部分,是现代地层学研究的重要步骤. |
| 关 键 词： | 化学地层划分 地球化学异常层 地层地球化学对比 |

| Abstract: | With the contents of 44 sorts of elements in regional rocks and strata of Hebei Province as the research object and the optimal partition of ordered geological quantity as the means, the authors divided the chemical strata and determined their boundaries. Moreover, carding and search of geochemical anomalous beds were done, and geochemical correlation of regional strata was made, which led to the construction of the regional geochemical framework. This research is an important component part of multiple stratigraphic division and also an important step in the modernization of the stratigraphic research. |
| Keywords: | division of chemical strata geochemical anomalous bed geochemical correlation of strata |
