Abstract: The paper introduces the theory and method of high一resolution sequence stratigraphy based on thecontrol of baselevel rise and fall. On the basis of fades analysis the method is used to deduce a single di-rection of accommodation migration, stacking patterns of strata, baselevel rise，and f all and s u dace to ca-tion of sequences by volumetric partition of sediment and facies differentiation, and to divide various or-ders of baselevel cycles(i. e. sequences) and to correlate thecycles order by order from long一termcyclesto short- term ones. After that, the authors apply the method for detail division and correlation of LatePaleo zoic coal-bearing series mainly composed of continental sediments in the Datong region，NorthShanxi, and clarify some vague conclusions and searches for the relationship between coal accumulationand high一resolution sequence. The result of the study indicates that the method can be widely used toimprove the precision of division and correlation of strata, and that it is an effective way to research intocontinental sequence stratigraphy. In addition, this approa his also very useful in correlation and predica-ti on of res erv airs.
