| 摘 要： | 本文的研究材料来自西藏羌塘高原西部台错古湖一个3.69 m的天然剖面,其地层测年为32.6-4.5ka.从其156个样品中获取大量的轮藻类、介形类和腹足类及少量有孔虫等微体化石.据轮藻类藏卵器外形,顶部结构、螺旋细胞钙化式样等特征,该剖面的轮藻类应归属于轮藻科Characeae之轮藻属Chara.经研究得知,台错古湖在...

| Abstract: | The materials in this paper come from a natural section of 3.69 m depth and 32.6—4.5 ka B.P.in the Taicuo ancient lake,western Qiangtang Plateau,Tibet.From 156 samples obtained there abundant microfossils have been found such as charophyte,ostracod,gastropod and foraminifera.Based on the shape,apical structure and spiral calcification of the gyrogonites,the charophytes from the section all belong to Chara.During a period of 28 ka in the Taicuo ancient lake there occurred 22 species of charophytes among which are 8 new types including 4 new species: Chara platea,Ch.gemma,Ch.subnana and Ch.taicuoensis and one variety: Chara convex var.zangbeiensis.The rest are Quaternary Chara members seen worldwide,including 5 new combination species: Chara alba(Mdler et Staesche),Ch.daqaidamensis,Ch.quanjiensis,Ch.longistipitata and Ch.tartensis.The multi-kind microfossils such as charophyte,ostracod and gastropod closely coexist there,which shows important significance in the ecological study of the charophyte flora. |
