| 摘 要： | 贵溪盆地罗塘群层序地层特征的研究表明,罗塘群由低水位体系域、水进体系域、高水位体系域组成,是一个完整的三级层序,自下到上可以划分为35个准层序,9个准层序组,准层序的形成是由于短期内的湖水深度的变化,这种短期内的湖水深度变化可以发生在水进期,也可以发生在高水位期,控制罗塘群三级层序形成的主要因素是构造活动和气候变化.在对罗塘群层序地层分析的基础之上,建立了贵溪盆地的层序地层模式.

| Abstract: | The characteristics of sequence stratigraphy of the Luotang Group in the Guixi basin indicate that the Luotang Group is made up of low water-level system tract, transgressive system tract and high system tract, and is an intact three-order sequence, which can be divided into 35 parasequences and 9 parasequence sets. The change of lacustrine water depth in short period that controlled the formation of the parasequence could occur in the transgressive system tract period, and also in the high system tract. The climate and tectonic activity were the important factor to the formation of the three-order sequence. Based on the analysis of sequence stratigraphy, the sequence stratigraphy mode is established for the Guixi basin. |
