| 摘 要： | 基于层序地层研究,区内聚煤作用主要发育于三级层序SQ1,SQ3,SQ4海侵体系域中,发育"根土岩—煤—粉砂岩/泥质粉砂岩/粉砂质泥岩/石灰岩"序列。海侵作用早中期,较高的泥炭堆积速率与可容纳空间增加速率相平衡,沉积了区域稳定分布的厚煤层6,14和29号煤层,最大海泛面附近的煤层较薄甚至不发育。

| Abstract: | Based on the study of sequence stratigraphy, coal accumulation mainly developed in thirdorder sequences as SQ1,SQ3 and SQ4. The sequence of root soil rock coal siltstone, rgillaceous siltstone, silty mudstone and limestone also developed in this area. In early and middle period of sea intrusion, due to the balance between high equilibrium rate of peat accumulation and increasing rate, No.6, 14 and 29 thick coal seam with regional and stable distribution deposited in this area. The coal seam near the maximum marine surface were thin and even not developed. |
