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。
Taking a combination of research methods, a detailed study on the coal-bearing plants of No. 16 coal seam in Yanzhou Coalfield in Shandong Province was carried out. Studied the coal-core flora in No.16 coal seam, and also conducted a detailed study on the coal-forming flora and its vertical evolution through pollen analysis and dissection of stratum corneum. Based on the study of coal plant in coal-rock sheet, the coal-bearing flora of No.16 coal seam was restored according to the appearance of the flora before and after the coal-forming period reflected by the large fossils of the coal series strata. The role of these research methods in reflecting coal plants and their evolution is analyzed and discussed. Only through this comprehensive study can we accurately reflect the appearance of coal-forming flora and its changes during coal formation.
