高分辨率层序地层学认为地层基准面的周期性变化控制了层序的形成及其内部地层构成样式 ,通过露头、测井和岩心资料上不同级次的基准面旋回的划分和对比 ,可构建等时地层格架。该方法在华北地区二叠系上石盒子组地层分析中取得了良好效果 ,在非海相地层的高分辨率地层对比、分析中具广阔的应用前景。 High-resolution sequence stratigraphy considers that the periodic variation of the formation datum controls the formation of the stratigraphic sequence and the formation pattern of its internal strata. According to the division and contrast of different levels of datum cycles on the outcrop, well logging and core data, Construction of isochronous stratigraphic framework. This method has achieved good results in the stratigraphic analysis of the Upper Shihezi Formation in North China, and has broad application prospects in the comparison and analysis of high-resolution strata in non-marine formations.
