    新疆哈密拗陷北部早侏罗世地层及其孢粉组合

    Early Jurassic strata and sporopollen assemblages in the northern Hami depression,Xinjiang

      摘要
    • 摘要: 哈密拗陷北部下侏罗统按其岩性、化石组合和地震波组等特征自下而上分为八道湾组和三工河组.根据两组所产的孢粉化石,建立了两个孢粉组合Osmundacidites Apiculatisporis Cycadopites组合和Cyathidites Pinuspollenites Cycadopites组合.根据孢粉组合特征及其对比,探讨了八道湾组和三工河组的地质时代.

       

      Abstract: On the basis of the lithology, fossil assemblages and seismic wave groups, the Lower Jurassic in the northern Hami depression may be in ascending order into the Badaowan Formation and Sangonghe Formation.According the sporopollen fossils,two sporopollen a
