摘要
在华南造山带江西萍乡下寒武统牛角河组泥质板岩和湖南永州中奥陶统烟溪组硅质岩中首次发现放射虫。放射虫的发现表明萍乡—永州一带寒武纪—中奥陶世存在相当规模的处于低纬度的海盆。
Radiolaria fossils were discovered for the first time in the lower Cambrian and middle Ordovician strata of the South China orogenic belt.They occur in argillaceous slate of the lower Cambrian Niujiaohe Formation in Pingxiang of Jiangxi Province and silicalite of the middle Ordovician Yanxi Formation in Yongzhou of Hunan Province.The discovery of Radiolaria shows that there might have existed a low-latitude sea basin of considerable scale in Pingxiang-Yongzhou area in Cambrian-Ordovician period.
