A Brief description on the classification and geological significance of sedimentary basins
The classification of sedimentary basins should focus not only on the principles of tectonic types but also on the evolution of basins.From different perspectives,the term “basin has different meanings.After the sediment accumulation,the basin formed by the crustal movement transformation is called “structural basin,also known as “post-deposition basin,such as large syncline,mantle and so on.There are also several different versions of the definition of sedimentary basins,one is that the sedimentary basin is in a certain geological period and in an independent geographical area in a relatively uniform tectonic setting from one or more sediment sources,the sediment consists and is composed of sedimentary rock masses.Another definition is: a settlement system containing sediments more than km thick,which now retains its original shape more or less.The classification and geological significance of sedimentary basins need to be studied in detail.
