Thinking of International Sequence Stratigraphy Development and L-H-T Sequence Stratigraphy
LI Shao-hu · Chenji xuebao · 2010
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) .
