摘要
在新疆库车地区硅质岩地层中发现了丰富的保存良好的放射虫化石,共计17属37种,包括一新种。并在此基础上,建立了5个放射虫组合带。该放射虫动物群的多数分子曾见于德国的Flandkenwald地区和美国Alaska和Ohio页岩中以及我国广酉。通过大量资料的分析对比,确定该套放射虫组合时代为晚泥盆世—早石炭世,进而阐述了这套放射虫硅质岩的大地构造意义。
Abundant well-preserved radiolaria were discovered in the silicate formations of Kuqa,accouting for 17 genus and 37 species including one new species. Five radiolaria association belts were so built. Most elements of the radiolaria fauna were seen in the shales of the Flandkenwald area of Germany,Alaska and Ohilo areas of U. S.,and in Guangxi of China. The analysis and comparision revealed the age of the radiolaria assemblage to be late Devonian to early Carboniferous. The geotetonic significance of the radiolaria silicates was then discussed.
