摘要
在１：５万区调对屯溪－休宁中生代盆地各类陆相沉积建造基本层序的调查基础上，对相应的沉积环境、沉积相进行了分析描述，根据主要受构造作用控制的各类界面将侏罗－白垩纪地层划分为四级地层层序；按照不同的沉积体系空间配置与层序样式的关系，划分了相应的陆相沉积体系域，对红层盆地进行了层序地层学分析。
Based on 1:50000 scale regional survey of the basic succession of variety of terrestrial facies depositional formations in theMesozoic Tunxi - Xiuning Basin, this paper has described and analyzed the corresponding depositional environment and depositional facies, and divided the Jurassic - Cretaceous strata into 4 - grade stratigraphic sequence in light of interfaces majorly controlled by tectonic process. And the corresponding terrestrial facies depositional system tract has been delimited and sequence stratigraphic analysis has been made on the red -bedded basin according to different relationship of sparial distribution of depositional system with sequence style.
