摘要
对六号煤层近七千粒孢粉的系统分析，建立Ｇｕｌｉｓｐｏｒｉｔｅｓ－Ｔｈｙｍｏｓｐｏｒｉｔｅｓ－Ｃｙｃｌｏｇｒａｎｉｓ－ｐｏｒｉｔｅｓ－Ｌａｅｖｉｇａｔｏｓｐｏｒｉｔｅｓ－Ｆｌｏｒｉｎｉｔｅｓ组合，并进一步建立了煤层上中下的分段亚组合：ｃ．Ｇｕｌｉｓｐｒｉｔｅｓ－Ｔｈｙｍｏｓｐｏｒｉｔｅｓ亚组合ｂ．Ｇｕｌｉｓｐｏｒｉｔｅｓ－Ｔｈｙｍｏｓｐｏｒｉｔｅｓ－Ｆｌｏｒｉｎｉｔｅｓ－Ｃｙｃｌｏｇｒａｎｉｓｐｏｒｉｔｅｓ亚组合ａ．Ｃｒａｓｓｉｓｐｏｒａ－Ｆｌｏｒｉｎｉｔｅｓ－Ｌｙｃｏｓｐｏｒａ－Ｌａｅｖｉｇａｔｏｓｐｏｒｉｔｅｓ亚组合α亚组合指示时代为石炭世，ｃ亚组合指示时代二叠纪，ｂ亚组合属于过渡类型。据此对本区含煤地层进行时代划分并与区内外对比。
After systematically analyzed about 7000 sporopollens of No,6 coal seam,an as-semblage of Gulisporites-Thymosporites-Cyclogranisporites-Laevigatosporites-Floriniteshas been established. The author then proceeded to divide the assemblageinto 3 subassem-blages:c, Gulisporites-Thymosporitesb. Gulisporites-Thymosporites-Florinites-Cyclogranisporitesa. Crassispora-Florinites-Lycospora-Laevigatosporites The″a″subassemblage indicates the age of Carboniferous,the″c″Permian, while the″b″subassemblage is transitional type.On these grounds,the age of coal-bearing strata inthe region was then dated and correlated inside and outside of Inner Mongolia.
