沉积环境分析是聚煤作用分析的基础,而层序地层分析又为沉积环境的分析以及含煤岩系的划分和对比提供了解释的基础。对贵州省六盘水煤田晚二叠世含煤岩系沉积环境进行分析,并对其关键层序界面进行识别,提出区内层序地层格架,恢复各层序的沉积环境,最后对区内聚煤作用控制因素进行分析,提出了区内晚二叠世基于层序—沉积相的聚煤规律。

Analyzing sedimentary environment is the foundation of the analysis coal-accumulating processes.Sequence stratigraphic analysis provides the foundation of explanation for divided and contrasted of coal measures and sedimentation control factor analysis.This paper analyzes sedimentary environment of coal bearing,identifies key sequence boundary,proposes sequence stratigraphy frame and recover sedimentary environment within sequence.Based on these,control factor on coal accumulation in research area was studied and coal accumulation on sequence-sedimentary facies of Late Permain was proposed.
