The Study Of Flysch In Diyanmiao Temple Of Inner Mongo

The Inner Mongolia Diyanmiao flysch of recently new discovery which is the thicksedimentary rules strata is composed of interbedded sandstone and slate, sandstoneintercalated with slate,slate intercalated with sandstone, interbedded sandstone and slateintercalated with relatively conglomerate or coarse sandstone(partial visible limestoneinterlayer), which is located in the Central Asian Orogenic Belt.The Inner Mongolia Diyanmiao flysch of Large thickness showed a set of rhythmicfeatures by sandstone and slate,which presents obviously turbidite character and lessrock types, mainly made up of sandstone, slate and mudstone, Secondary to siltrock，conglomerate and limestone. Diyanmiao area develops typical Bouma sequence but notcompletely and mainly Tb、TdandTe Formation, Tc Formation exposed in part layer.Thisarea develops many similiar but different sedimentary rules repeated emerge.But it is notconsist of a series of continuous sedimentary rules only,wo can see the thicknon-rhythmic layer among rhythmic layer,so the rhythmic layer and the non-rhythmiclayer form the Cyclic.The Sedimentary structures is upgrowth in Diyanmiao, the trough mold,all kinds ofstratification, the Wave traces and the structures of organism is common.The trough moldis not only one of the Feature constructions,but also is one of the ImportantConstructions of Show the bottom.The Flame-like structure is produced byLiquefaction,it is also one of the Constructions of Show the bottom.The Trace fossils aredevelop,and mainly attribute Nereites.The Common trace fossils are mainlyHelminthoida, Cosmorhaphe、Chondrites、Zoophycos and so on.The fossils aremainly sea lily stem, Brachiopods and Gastropods and so on.Through chip analysis and geochemical analysis for Diyanmiao flyschsandstone,getting the fit consequence which is greywacke. From the analysis of constantelements indicates that plate tectonics background of Diyanmiao area flysch is thecontinental island arc type.
