Abstract

The Pemo-carboniferous epicontinental coal-accumulating basin in North China differs greatly to the continental marginal sea basin of North America in geological condition. The episodicity and eventness of transgression, the extensiveness and isochroneity are good surfaces for the classification of internal architectural units in sequence. Study shows that the architecture of sequence in the Pemo-carboniferous epicontinental coal-accumulating basin in North China is “dualistic pattern”, that is, “transgrassive-highstand”, lack of lowstand system tracts. The transgressive system tracts are composed of one to two parasequences, and highstand system tracts consist of more than two parasequences. The system tracts are all just corresponding to parasequence set. Transgrassive parasequence sets are weak retrogradational-aggradational type and the highstand system tracts are weak progradational-aggradational type. The parasequences are high precision map-compiling unit. They can provide reliable basis for the analysis of sequence frame and coal accumulation.
