| Abstract: | Based on the 60 evenly distributed stratigraphic profiles in North China platform andtheir integrity of Late Palaeozoic aggregational coal basins,the multiple classification of LatePalaeozoic strata of North China have been made out. In rock-stratigraphic aspect,18 rockstratigraphic units "Formations" were divided,and the diachronism of formation has beendiscussed F In biostratigraphic aspect,selveral assemblage zones, range zones and acme zonesof fusulinids,paleoplants and sporopollens were divided, and the organic evolution series,space distribution and correlation were analysedl in chronohorizon aspect, according to theconception of boundary stratotype and the correlativity of the main biostratigraphic unitboundary,the authors have discussed several chronohorizon boundaries which include theboundary between Carboniferous System and Permian System, and the inner boundray between Carboniferous System and Permian System with regard to the common internationalstage names, and established a systematic chronostratigraphic sequence of Late Paleozoic Eraof North China platform. |
