Abstract: There are extrathick high quality coal for liquidation oil in the Xianfeng basin, Yunnan Province, China. There are abundant sedimentary marks of allochthonous genesis in the extrathick coalbeds. These genetic indicators reveal two new submodels about allochthonous accumulation: that is, "the river distant transport of plant detritus→the sedimention of plant detritus fan delta or plant detritus delta + the allochthonous sedimention of lacustrine drift plant detritus + the hypautochthony accumulation of local lakeshore swamp peat + the autochthonous accumulation of local lacustrine algae peat + the sedimention fine detritus→the mix and transport because of flood current or weak storm flow or underwater gravity flow→the mechanical differentiation and resedimentation of plant detritus and inorganic detritus’, can be recapitulated. It can be deduced to the twice accumulation of lacustrine plant detritus fan delta and underwater gravity flow’or be reduced to Xianfeng submodel’. This submodel supplements the allochthonoushypautochthony lacustrine combination accumulation model’ of the extrathick coalbeds of Fuxin submodel and Fushun submodel in Chinese Mesozoic and Cenozoic intracontinental fault basin.
