Abstract


Due to the limit of research technique, method and many other factors, there are really few research was involved in sporopollen assemblage, ancient vegetation and paleoclimate of Carboniferous and Permian in Tengxian coilfield, Shandong province, since it was discovered and investigated. Therefore, the study results in this area were immature and incomprehensive. Expect for the continuous study on the stratigraphic sequence, the environment of deposition, the formation background and coal gather rule to the stratum of coal containing for the area and the co relational area. The research to Neopaleozoic sporopollen assemblage, ancient vegetation and paleoclimate evolution rule to the area was to supply a gap and enrich the research materials on Carboniferous-Permian sporopollen assemblage and paleoclimate.112 genus and about 473 species was discovered by analyzing and appraising the sporopollen fossils. According to the longitudinal distribution and vertical variation the main genus and species of sporopollen fossil, it can be divided into 5 assemblages as following (in descending order):Ⅴ. Triquitrites-Macrotorispora cathayensisⅣ. Patellisporites meishanensis- Torispora securisⅢ. Gulisporites cerevus-Sinulatisporites shanxiensisⅡ. Thymospora pseudothiessenii-Laevigatosporites vulgarisⅠ. Crassispora kosankei-Densosporites anulatusThey respectively occupied ( in descending order ) Shangshihezi Formation , Xiashihezi Formation of Shihezi series and Shanxi Formation , Top Taiyuan Formation of Yuemengou series(Permian) as well as Hypomere Taiyuan Formation of upper Carboniferous. The feature of each sporopollen assemblage was analysed and matched with co relational area and some area of north China; sporopollen flora, ancient vegetion and paleoclimate was generalized and analysed
