Late Paleozoic strata in northeastern China are distributed in a zonal pattern around the old-land on the Jiamusi-Mongolia Block�� They are composed of active deposits in the regular distributed tectonic lithofacies zones�� This indicates that the late Paleozoic strata belong to continental margin deposits�� According to the strong conformability of the sedimentary strata in the same continental margin and distinct differences among the three continental margins��three stratigraphical regions of the Jiamusi-Mongolia Stratigraphical Province are recognized along the northern��southern and eastern margins of the Jiamusi-Mongolia Block��named respectively as Xing'an Stratigraphical Region��Inner Mongolia grass--Songhua River Stratigraphical Region and Baoqing--Hunchun Stratigraphical Region�� Due to the characteristics of continental margin deposits and active sediments��the strata can be correlated on the level of formation by the methods of analysing the rock association in the same stratigraphic region�� Therefore��some revisions of the lithological formations of the late Paleozoic strata in northeastern China have been made��and a new chart of lithostratigraphic correlation has been proposed�� Furthermore��the present stratigraphic framework is setting on the International Stratigraphic Chart on the level of stage��after comprehensive researches to lithostratigraphy��biostratigraphy and chronostratigraphy��especially the conodont biostratigraphy and isotopic ages of volcanic rocks obtained in recent years��
