详细研究了北京地区与窑坡组有关的岩浆岩和火山碎屑岩的岩性和分布特征以及对窑坡煤系的影响。认为窑坡组形成前的火山喷发,为煤系的形成提供了基底,并引起抢峰坡和葫芦棚等地隆起;窑坡组形成过程中的火山喷发,喷出的火山物质使湖泊淤浅,在淤浅处发育泥炭沼泽而成煤;窑坡组形成后的岩浆侵入使窑坡煤系受到了破坏。
The lithology and distribution characteristics of magmatic rocks and volcaniclastic rocks related to the YaoPo Formation in Beijing area and their effects on the coal measures of the slope slopes are studied in detail. It is considered that the volcanic eruption before the formation of the Kao Slope Group provided the basement for the formation of coal measures and caused the uplift of the Qiangfeng Slope and the Gourd Shed. The volcanic eruption during the formation of the Yaopo Formation led to the volcanic eruption of the lake , In the shallow sediment peat bog and the development of coal; magmatic intrusion after the formation of the Kiln slope to the coal slope of the slope was destroyed.
