海拉尔盆地群下白垩统层序格架内聚煤特征与成煤模式
Coal–accumulating and coal-forming patterns within sequence stratigraphy framework of Early Cretaceous in Hailar basins
摘要
Abstract
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 sequenceⅢ andⅥ were developed with majorcoal. In the se-quence, coal seams were developed regularly, from alluvial plain to upper delta plain, lower delta plain and lacustrine en-vironment. 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 sequenceⅢ andⅥ .关键词
