通过对大同石炭-二叠纪煤系沉积物的碎屑特征分析,提出沉积物来源方向和陆源区域位置,揭示陆源区构造背景的演化对沉积物源组分的影响,为大同进行古生代煤岩层对比、预测煤层厚度变化规律等提供了依据。
Based on the analysis of the detrital characteristics of Datong Carboniferous-Permian coal measures, the source direction of sediments and the location of terrestrial source areas are proposed to reveal the influence of the tectonic evolution of terrigenous regions on the composition of sedimentary source rocks. Contrast and predict the law of coal seam thickness provides the basis.
