摘要
窑坡组是北京地区的重要含煤地层,形成于构造稳定的河流—湖泊体系,浅水湖泊三角洲发育。聚煤可概括成三种模式,主要煤层形成于废弃的三角洲平原上。
Yaopo Formation is the important coal—bearing strata in Beijing area. It was Formed in the fluvial—lacustrine system under the stable tectonic setting. The shallow lacustrine delta deposits are main parts of Yaopo Formation. Coal accumulation is summarized as three kinds of model. The main coal beds were formed in the abandoned shallow lacustrine delta.
