摘　　要：本文研究了吐哈盆地第三系─白垩系各层位的孢粉、介形类和轮藻化石分布特征。其中早白垩世吐谷鲁群的孢粉化石为克拉梭粉属Ｃｌａｓｓｏｐｏｌｌｉｓ─双束松粉属Ｐｉｎｕｓｐｏｌｌｅｎｉｔｅｓ─原始松柏粉属Ｐｒｏｔｏｃｏｎｉｆｅｒｕｓ组合，介形类为女星介组合，轮藻仅个别见开口轮藻化石。早第三纪鄯善群的孢粉为栎粉属Ｑｕｅｒｃｏｉｄｉｔｅｓ─唇形三沟粉属Ｌａｂｉｔｒｉｃｏｌｐｉｔｅｓ─圆形稀沟粉Ｓｔｅｐｈａｎｏｃｏｌｐｉｔｅｓｒｏｔｕｎｄｕｓ组合，介形类仅见真星介未定种Ｅｕｃｙｐｒｉｓｓｐ．化石，含一定量的轮藻化石，有长卵形轮藻（相似种）Ｃｈａｒａｏｆ．ｌｏｎｇｏｖａｔａＰａｐｐ和球形拟丽藻ＮｉｔｅｌｌｏｐｓｉｓｇｌｏｂｕｌａＭａｄｌｅｒ等；桃树园组孢粉为拟白刺粉属Ｎｉｔｒａｒｉａｄｉｔｅｓ─麻黄粉属Ｅｐｈｅｄｒｉｐｉｔｅｓ─藜粉属Ｃｈｅｎｏｐｏｄｉｐｏｌｌｉｓ组合，未见介形类和轮藻化石。晚第三纪葡萄沟组孢粉为藜粉属Ｃｈｅｎｏｐｏｄｉｐｏｌｌｉｓ─蒿粉属Ａｒｔｅｍｉｓｉａｅｐｏｌｌｅｎｉｔｅｓ组合，介形类化石有近球形金星介比较种Ｃｙｐｒｉｓｏｆ．ｓｕｂｇｌｏｂｏｓａＳｏｑｗｅｂｙ和苏氏小玻璃介比较种Ｃａｎｄｏｎｉｅｌｌａｏ?Distribution characters and assemblages of fossils of sporo-pollen, ostracoda and Charophyte from Cretaceous to Tertiary in Turpan-Hami basin are studied in this paper. Sporo-pollen assemblage in Tuguolu group of lower Cretaceous is Classopollis-Pinuspollenites; Charophyte is mainly Cypridea and a little of Charophyte can be seen, for example, Aclistochara. In Shanshan group of Eogene sporo-pollen assemblage is Quercofdites-Labitricolpiyes-Stephanocopites rotundus, only Eucypris sp. found and with some Charophyte fossils, e. g-Chara of. longovata Papp and Nitellopsis globule Madler etc. Sporo-pollen assemblage in Taoshuyuan formation is Nitrariadites-EPhedripites, but Ostracoda and Charophyte fossifs are not found.Sporo-pollen assemblage of Putaogou formation of Neogene is Chenopodipollis-Artemisiaepollenites and Ostracoda fossils are Cypris of. Subglabosa Soqweby and Candoniells of. suzini Schnoiddr. Above research is very useful for division and correlation of strata in this basin and ends the 'barren-strata' history of the above group and formations.
