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.
