| 摘 要： | 研究了开平－涧河地区主要含煤地层之一－山西组的沉积特征，介绍了山西组沉积演化特点，提出了山西组为受海泛作用影响的浅水三角洲沉积，指出聚煤作用及煤层布主要受沉积环境控制，与海侵密切相关，认为聚煤作用主要形成于废弃三角放间湾充填变浅背景上发育起来的泥炭沼泽环境。 |
| 关 键 词： | 聚煤 海浸 山西组 开平－涧河地区 沉积 煤矿床 |

| Abstract: | Shanxi Formation is one of the main coal-bearing strata in Kaiping-Jianhe area. The field and laboratory studies show that Shanxi Formation is a shallow water delta deposition mainly influenced by ingression. The sedimentary evolution of Shanxi Formation was discussed. Coal accumulation and coal bed distribution were controlled by sedimentary environment and were closely related to regression. Coal accumulation occurred mainly in the peat swamps developed on the base of abandoned delta and filling-shallowed delta distributary bay. |
| Keywords: | shallow water delta coal accumulation ingression Shanxi Formation Kaiping-Jianhe area |
