摘    要:根据地层露头和钻孔资料揭示,运用高分辨率层序地层学理论和方法,对兴隆含煤区石炭二叠系进行研究,划分了短期、中期、长期基准面旋回。研究区短期基准面旋回类型是以基准面上升为主的不对称旋回,共识别出短期旋回8个,中期旋回5个,长期旋回2个。研究区发育典型的边缘相组合,包括冲积扇沉积组合、辫状河三角洲平原组合及渴湖一泛滥盆地组合,分析了各组合相沉积特征,并讨论了层序界面选取原则及煤层在层序划分中的意义。该成果对于在研究区及外围寻找新的煤炭资源具有一定参考价值。

关 键 词:石炭-二叠系  相组合  层序划分  兴隆

Abstract:Based on outcrops and borehole data, the principle of the sequence stratigraphy was used to reconstruct sequence stratigraphic framework of the Permo-Carboniferous system in Xinglong coal-bearing area. Three base-level cycles were identified, they are 8 short-, 5 middle- and 2 long-term cycles. Furthermore, the short-term cycles are dissymmetrical and mainly rising cycles. Typical marginal facies associations were developed in the study area, they are alluvial fan, braided river delta plain and lagoon-flood basin associations. The paper analyzed sedimentary features of each association and discussed sequence boundary identification principle and significance of coal seam in sequence division. The results can be used to find new coal resources in study area and periphery.
Keywords:Permo-Carboniferous  facies association  sequence division  Xinglong
