Abstract：Lithostratigraphic digitalization and visualization is the foundation of digital stratigraphic research.It is also the first step to extricate stratigraphy from traditional discrete description and explore the new concise scientific methods.Regarding the basic lithostratigraphic units as “lithostratigraphic cells”,this paper explores a geological process in which a simple sedimentary sequence,through erosion,transformation,burial and diagenesis,eventually forms a variety of complex stratified rock series. A new theory,procedure and technical method for defining the lithostratigraphic units of the Liangjiashan Formation is presen-ted in this study.The one-dimension digital description of Liangjiashan Formation is fulfilled by an independently developed software platform,RSD.The survey confirms that the conclusion drawn from virtual computation is consistent with that of the field geological investigation.The digital description of the Liangjiashan Formation reveals that its lithostratigraphic records in different regions have originated from the same basic lithostratigraphic units even though their appearances differ significantly from each other.The results provide a theoretical basis and technical feasibility for the quantitative description of such details as the motion amplitude and rate of ancient basin system,which can not only save both outdoor and indoor repeated workload,but also can help dig deeper into the information stored in the rock strata.
