摘要(Abstract):
对内蒙古海拉尔盆地早白垩世含煤岩系的沉积充填序列、层序地层及聚煤规律进行研究,将扎赉诺尔群划分为6个3级层序及相应的体系域,6个层序分别对应于铜钵庙组、南屯组一段、南屯组二段、大磨拐河组一段、大磨拐河组二段和伊敏组,煤层主要发育在层序Ⅲ、Ⅵ的湖侵体系域;且煤层在层序格架内部,从辫状河冲积平原–上三角洲平原–下三角洲平原–湖泊环境,呈现有规律的变化。通过对层序Ⅲ、Ⅵ中各主采煤层的底部砂体厚度、煤层厚度及成煤期的古地理环境详细分析,概括出层序Ⅲ的主要成煤环境为湖泊周缘扇(辫状河)三角洲平原和湖滨带;层序Ⅳ主要聚煤环境为扇前、扇间浅水湖盆和浅水湖泊大面积淤积而成的泥炭沼泽。
This paper analyzed the basin–filling sequences, sedimentary sequence and coal accumulation pattern. 6 third–order sequences were divided in the Zhalainuoer Group, which respectively correspond to Tongbomiao Formation, the first and second member of Nantun Formation, the first and second member of Damoguaihe Formation and Yimin Formation. The lacustrine transgressive systems tracts in sequence and were developed with major Ⅲ Ⅵ coal. In the sequence, coal seams were developed regularly, from alluvial plain to upper delta plain, lower delta plain and lacustrine environment. Based on the study of the thickness of the main seams, base sandbody and the paleogeographic environment in the coal-forming period, two kinds of coal accumulating modes were summarized in the sequence and Ⅲ Ⅵ.
