| 摘 要： | 在内蒙古中部达尔罕茂明安联合旗北西靠近国境线的巴彦敖包地区硅质岩中首次发现早二叠世晚期—中二叠世早期的放射虫化石,放射虫化石包括4个属的6个比较种和若干个未定种:Pseudoalbaillella cf.lomentaria,P.cf.rhombothoracata,P.cf.scalprata,P.cf.longicornis,Latentifistula cf.patagilaterala,Ruzhencevisponguscf.uralicus,Stigmosphaerostylus sp.等。该区系索伦山蛇绿构造混杂岩带的东延部分,该动物群的发现提供了索伦山蛇绿构造混杂岩带最终混杂堆积的时间为中二叠世早期的证据。 |

| Abstract: | The radiolarians were found in the Lower Permian siliceous rock of the Bayanaobao area on the eastern Solon Mountain of northwestern Darhan Muminggan, Inner Mongolia. This fauna is interpreted as late Early Permian (Cisuralian) to early Middl Permian (Guadalupian) in age. It contains the following 6 conformis species in 4 genera: Pseudoalbaillella lomentaria, P. cf. rhombothoracata,P. cf. scalprata,P. cf. longicornis, Latentifistula cf. patagilaterala, Ruzhencevispongus cf. uralicus, Stigmosphaerostylus sp.. The discovery of this fauna proves that ophiolitic mélange exposed on the eastern Solon Mountain was finally formed in the early Middl Permian. |
