The paleogene tectonic sequence analysis based the characteristics of lithofacies and palaeogeography in lanping basin,yunnan

Mapping lithofacies palaeogeography based on tectonic sequence is to combine the research of lithofacies palaeogeography,sequence stratigraphy, tectonic development and evolution. Using identified sequence boundaries and other key boundaries as relative equivalent time horizons in order to classify the systems tract as the units of mapping,then get the compressed lithofacies palaeogeography. Using this method of mapping in Lanping Basin during the Paleogene can reveal and understand the relationship between tectonic movements, sedimentary characteristics and changes of lake level, further recognize the characteristic of time-space evolution in this area.
