【摘要】 采取多种手段相结合的研究方法，对山东兖州煤田16号煤层的成煤植物进行了详细的研究。研究了16号煤层中的煤核植物群，还通过孢粉分析及分散角质层的研究，对成煤植物群及其在垂向上的演化进行了细致的研究。结合煤岩光片中煤植体的研究，并对照煤系地层大化石所反映的成煤期前后的植物群面貌恢复了16号煤层的成煤植物群。分析并讨论了上述研究方法在反映成煤植物及其演化方面的作用，认为只有通过这种综合研究才可以较准确地反映成煤植物群面貌及其在成煤过程中的变化。更多还原

【Abstract】 Multi - methods are used in this paper to make a detail study upon the coal - forming flora of No. 16coal - seam in Yanzhou coalfield, Shandong province. These methods include the study of the coal- ballplants, the analysis of the sporo- pollen and separated dispersed cuticle layers from the coal - seam, and thebrief study on the phyterals in the coal - seam. Through all these studyings, and by the comparison with thegeneral flora appearances of the pre - and post coal - forming stages which are reflected by the mega - fossilsfrom the coal measures, the coal - forming flora and its vertical evolutionary history are finally rebuilt. Theresults got from the above different methods are discussed and analyzed, and it is to be thought that only fromsynthetically study on the coal - forming flora with different methods, can the accurate result be obtained.更多还原
