Thinking of International Sequence Stratigraphy Development and LHT Sequence Stratigraphy

Key words: 
• LHT sequence stratigraphy

Abstract: Based on the research development in international sequence stratigraphy, this paper puts some viewpoints forward as follows: (1) sequence of seismic stratigraphy is different from the depositional sequence of sequence stratigraphy; (2) after 1992 the transformation from threedivided to fourdivided models, the difference between marine and continental depositional sequence makes sequence stratigraphy develop complicatedly; (3) the base level curve correlative to the fourdivided model of current sequence stratigraphy is nonperiodic and is not correlative to the periodicity of shoreline trajectory; (4) this paper introduces LHT sequence stratigraphy including conceptual model, diagrammatizing rules and approach of chronsequence framework, revamped base level curve correlative to systems tracts of LHT sequence stratigraphy. This paper redefines sequence as "a relatively conformable succession of genetically related strata bounded by remnant maximum flooding surfaces (RMFS) and their correlative subaerial unconformities (CSU)".
