煤系地层岩性组合特征是地质勘探野外岩性对比、判定的基础。豫西石炭二叠系地层为主要含煤地层,通过对煤系地层地质标志层的特征描述、地层沉积相及煤岩层组合规律的研究,为地层对比判定提供了一定依据。
The characteristics of lithologic assemblage in coal measures are the basis for the comparison and determination of lithology in the field of geological exploration. The Permo-Carboniferous strata in western Henan Province are the main coal-bearing strata. Based on the characterization of the geological markers of coal-bearing strata and the study of the stratigraphic sedimentary facies and the regularity of coal-rock strata combination, this study provides some evidences for the stratigraphic correlation.
