| 摘 要： | 充填于永康盆地内的永康群内陆河湖相沉积物，可划分为9种沉积类型，不同时期的沉积岩相组合和不同环境下的岩石学特征不尽相同，并可划出8种沉积总体，组成盆地沉积的基本构成单位。该盆地的6个主要地质界面，限定了盆地5个等时性地层单位，反映了盆地发展的5个演化阶段，称为5个沉积幕。沉积幕的叠覆，构成了永康盆地成因地层格架的整体样式。

| Abstract: | Yongkang Group, the fluviolacustrine deposit of Yongkang basin of a continental river, may be subdivided into nine sorts of sedimentation in which the sedimentation associations in different stages and the petrologic characteristics in different environments are not the same, or into eight sedimentary bodies, which are the basic units of the deposits in the basin. There exist six geological boundaries controlling five isochronous stratigraphic units, which indicate that the basin developed in five stages, or called five sedimentary episodes which compose of the model of genetic stratigraphic framework of Yongkang basin by means of overlapping each other on the whole. |

| Keywords: | Yongkang basin basic sequence sedimentary body sedimentary episode evolution stage genetic stratigraphic framework |
