Abstract: Mono-faulted lake basin was developed on one side of the continental faultdown in eastern China during early,middle and late evolution stages.Four sedimentary environments are recognized,i.e.areas of steep shelf,gentle shelf,lake center and the lake entry along long axis.There are 21 kinds of seismic facies models in 17 categories distributed sequentially.The characteristics of tne models are described,seperately.Because a central upl-ifting zone generally exists in double faulted basins,with depressions on both flanks comparable to mono-faulted basin.The models of seismic facies in eastern China could be summerized as mono-faulted models.
