滇黔桂盆地及其邻区的泥盆系包括下部的海侵碎屑岩系、中部的混合沉积地层和上部的碳酸盐岩地层,其中又可以进一步划分为13个三级沉积层序和两个二级构造层序。不同阶段三级层序的相序组构特征及其空间变化代表了不同的岩相古地理背景,形成了一个受海平面变化和区域构造运动共同控制的沉积盆地充填序列;同时也反映出研究区域三级海平面变化与欧美地区相对比存在较大的差异。
The Devonian in the Yunnan-Guizhou Gui Basin and its adjacent areas include the lower transgressive clastic rocks, the middle mixed sedimentary strata and the upper carbonate strata, which can be further divided into 13 tertiary sedimentary sequences and Two secondary structural sequence. The phase sequence structural features and their spatial variations of tertiary stages in different stages represent different lithofacies palaeogeographic background and a sedimentary basin fill sequence controlled by sea level changes and regional tectonic movements. At the same time, There is a big difference between the sea level change of the three regions and that of the Europe and the United States.
