| 摘 要： | 应用层序地层学的概念和方法，从沉积特征研究入手，对该区的含磷岩系——洋水组划分出5个沉积层序(旋回)，结合层序界面及层序的归纳描述，确定了层序类型，并认为洋水组是一套海进体系域中由一系列低级别退积型沉积层序(旋回)组成的高级层序(Ⅰ级))。

| Abstract: | With the approaches and theory of sequence stratigraphy applicable, in launching on a study on depositional features, five types of sedimentary sequences (i.e. cycle) are divided into for the phosphoric rock series of the Yangshui Formation at this zone, in association with sequence interface and its relative characterization, the types of the sequences are determined and the Yangshui Formation is considered a high-ranking I-level sequence that is constituted by a series of low-grade retrograding type of depositional sequences within the transgressive system. |
