摘　　要：河南伊川盆地屯2井、屯3井谭庄组、椿树腰组产以Hughesisporites gibbosus,Triletes vulgaris占优势的大孢子化石组合。该组合面貌显示其赋存地层的时代为晚三叠世,层位或可与新疆准噶尔盆地、塔里木盆地的黄山街组对比。大孢子化石组合的发现对整个洛阳-伊川地区探井地层划分、对比具有重要意义。The Hughesisporites gibbosus-Triletes vulgaris megaspore assemblage from the Tanzhuang and Chunshuyao formations in Wells Tun 2 and Tun 3 of the Yichuan Basin,Henan Province,China has been recognized.According to the materials of megaspore assemblage and their distribution,the present study assigned the megaspore assemblage strata to the Late Triassic,which can be correlated with the Huangshanjie Formation in the Junggar Basin and Tarim Basin.The discovery of megaspores is significant for the stratigraphic subdivision and correlation in this area.
