| Abstract: | The term ecostratigraphic facies(abbreviated as EF)is presented for the first time inthis paper,which is defined as the association of fossils(including trace fossils)communityand sedimentary features in a given paleo environment.According to the association typeof fossils and sedimentary features,eight types of ecostratigraphic facieses have been pro-posed,i.e.supratidal type(EF1),intertidal(foreshore)type(EF2),subtidal(shoreface)type(EF3),upper shelf type(EF4),middle shelf type(EF5),low shelf type(EF6),bathyal type(EF7)and abyssal type(EF8).On the basis of the association law of ecos-tratigraphic facies in both space and time,lateral ecostratigraphic model including ecostratigraphic facies tract(EFT),ecostratigraphic facies region(EFR)and ecostratigraphicfacies system(EFS)as well as vertical ecostratigraphic model containing ecostratigraphicfacies zone(EFZ),ecostratigraphic facies formation(EFF)and ecostratigraphic faciesgroup(EFG)are described. |
