Abstract: The Carboniferous-Permian depositonal formation in North China Consists of mixed carbonate/siliciclastic coal-bearing formation and red siliciclastic rock formeration.The former formed in platform-barrier island complex system and shallow water delta system,and the latter formed in fluvial and lacustrine system. The outcrop sequence stratigraphic methodology was applied to research the Carboniferous-Permian depositional formation in North China.The results showed that there exists a special type 1 sequence boundary that lacks the incised valley and its fills in epeiric sea basin(the authors called it as type Ⅰe sequence boundary). The condensed sections are shallow water carbonate rock and siliceous sponge spicule rock or siliceous mudstone that formed at the period of sea-level rised rapidly.There are 4 kinds of parasequeuce that are bottom type,platform-barrier island complex type, siliciclasitc shoreline type and fluviolacustrine type parasequence. According to unconformities and other markes,the Carboniferous-Permian depsitional formation in North China is subdivided to 5 sequeces which belongs to 3 kinds of sequence stratigraphic models. Sequence 1,2and 3 are epeiric sea type sequences, their bottom are type Ⅰesequence boundary.The sequences developed only transgressive and highstand systems tracts, and the condensed sections are shallow water carbonate rocks with the properties of low hydrochloric asid nonsoluble residual,low content of trace-elements and high ratio of Fe2+/Fe3+.Each systems tract includes several parasequences.Most of them consists of limestone in basal, siliciclastic rock in middle and coalbed in top,which reflected the cycles of relative sea-level repidly rise up and slowly fall down. Sequence 4 is transition type sequence.Its bottom is type 1 sequence boundary,and the condensed section is shallow-water siliceous sponge spicule rock or siliceous mudstone with the thichness of 20-30cm.This sequence includes lowstand, transgressive and highstand systems tract. Most of the parasequences in the systems tracts ended with coalbed.Sequence 5 is the nonmarine sequence(red siliciclastic rock formation).Its bottom is type 1 sequence boundary,and includes lowstand,water transgressive and highstand systems tracts(as our personal work is limited.the parasequences are not subdivided at present). The development of Carboniferous-Permian basin-fill supper sequences in North Chena is controlled by second order sea-level change,and the development of depositional sequence mainly controlled by riginal orogeny.
