| 摘 要： | 通过对滇西保山盆地永铸街凸起的地震、钻测井和露头资料的综合研究,结合前人对保山盆地构造演化的研究成果,利用高分辨率层序地层学原理分析了保山盆地的构造演化特征。指出在保山盆地的演化过程中,由于盆地受到喜山运动的影响,造成该地区长期处于拉张或短期局部逆转挤压的环境中而不断地沉降或局部短期抬升,基准面也随之发生反复的升降变化,并引起了可容纳空间发生相应的增加或减少。认为盆地充填序列按古构造运动旋回可划分为3个超层序(或Ⅲ级层序组),并分别与盆地演化的阶段相对应,在超层序内部可划分出8个Ⅲ级层序。结合前人对保山盆地拉张史和沉降史的研究成果,以基准面旋回为研究基础,以超长周期基准面旋回为周期,以长周期为成因地层单元,论述了基准面变化与层序发育特征、层序分布模式、沉积体系类型和盆地充填演化序列及其与沉积相带的关系。

| Abstract: | By means of the data of drilling,outcrop,logging and high resolution seismal section,combining the conclusion that many scholars have studied on the evolution of tectonics and deposition,using the principles of the high resolution sequence stratigraphy,the article analyzed the characters of the evolution of tectonics in Baoshan basin of the west in Yunnan province,and divided high resolution strata sequences.During the evolution of Baoshan basin,it was being in longlasting extension or in shortdated extrusi... |
