The Early Cambrian Stratigraphic Correlation And Sedimentary Environment Analysis Of Xuzhou And Other Regions Nearby

Study area across three provinces of Jiangsu, Shandong and Anhui, main scopein northwest of Xuzhou, north of Suzhou and central and southern Linyi. EarlyCambrian strata outcropped in good condition. This region is ideal region and stratumstudy, in which has good base of the rock stratum, biology stratum, time stratum andsediment facies. Through the study of this paper, mainly has the following:On the basis of the early study result as well as new rock stratum cleaning upmind, early Cambrian stratums in the research region is studied completely. Identifiedincluding4category(Trilobita、Brachiopoda、Small shell animals、Trace Fossil) of17genera and21kinds of fossils. According to the time limit of the distribution ofvarious kinds of fossils and the contrast relationship, and combining the standardprofile data, four sections in the study area (Weiji, Liguan, huang, Mount Lv) fivelithostratigraphic units (Houjiashan Formation, Wushan Formation, Liguan Formation,Gouhou Formation, Jinshanzhai Formation) are classified as Canglangpu Stage.Lithostratigraphy, biostratum and depositional sequence are consolidated by the wholeregion stratum contrast in research field.According to characters of the rock types, sediment structure, palaeocommunite,section structure, etc. early Cambrian sediment system is divided shore sedimentsystem and tidal flat sediment system in the research region and erect sediment model.Lithofacies paleogeography were posted. On the production of researching tectonicevolve, the author iscussed the reason of sgression direction.
