Current situation and developing tendency of sequence stratigraphy

Sequence stratigraphy is based on seismic stratigraphy,loggeology,processo-sedimentary,paleozoology,iso tope geology and so on. It is a synthetical subject which mainly studies relations between relative lithological sequence and circled lithological sequence in chronoho rizon formation framework,and provides a new method by which division and correlatioon of sedimentary rock can be done in space. We can objectively build up vertical and lateral stack sequence of sedimentary rock with sequence stratigraphy.In the paper,the new estrecognization about basic principle and controlling factores of sequence stratigraphy is analysed.Moreover,the four developing tendencies of sequence stratigraphy a reprovided.
