| Abstract: | The Permo-carboniferous coal measures in Southwest Shandoug were formedin the North China epicontinental basin. Because of the specific characteristics of the basin-gentle slope and cast scope, the tidal flat may be regarded as an independent depositionalsystem. The paludification of tidal flat gives rise to the formation of important coalbeds.The authors give a detailed study ou the internal architecture,genetic facies of the deposi-tional system, analyse the sedimentary combination and their genetic units,go further intothe coal-accumulation and the formation and distribution of coal-rich wnits in the deposi-tioual system. |
