摘要
在分析临汝煤田煤系上覆地层P_2~2~T_1层段岩性特征、孢粉组合并与近邻剖面对比的基础上,将该地区煤系上覆地层剖面划分为二叠系上统石千峰组一、二、三段,三叠系下统金斗山组。这种划分方案可进行区域对比,而且使用方便,从而解决了找煤工作中煤系上覆地层划分与对比之难题。
On fhe basis of analysing the petrological character of overlying strata P_2~2~T_1 in Linru Coalfield and Sporo-pollen compound compared with adjacent sections, the overlying strata of coal-bearing series in the area is divided into Upper Permian Shiquanfeng Formation with 1, 2 and 3 members and Lower Triassic Jindoushan Formation. Such a division can be used to compare with regional strata and thus the problms in strata division and comparison of overlying strata are solved.
