摘　　要：运用沉积学有关基本原理,对该区山西组沉积体系进行了较为详细的成因地层学分析。识别出多种成因相及成因相组合,分别划归为两种不同的沉积体系,并详细地阐述了其各自的沉积特征及其意义。揭示了 D 煤层的形成背景、聚积规律及其变薄、缺失的沉积地质因素。对煤层对比及厚煤区分布预测具有一定的指导意义。Based on the principles of sedimentology,detailed analysis of genetic stratigraphy about the depositional systems of Shanxi Formation are given.A lot of genetic facies or genetic facies assemblages which are the architectural elements of two different depositional systems are recognized,and their detailed descriptions of sedimentary characteristics or their evironment significances are given.The analysis of coal—D accumulation have showed the sedimental geologic factors on coal thinning or absence.The discusses of this paper are useful in the application of coal correlation and prospecting areas of thick coal seam.
