| 摘 要： | 聂拉木是西藏南部志留纪含笔石地层(石器坡组)的主要产地。近期在该地亚来村新发现一批笔石标本, 包括Normalograptus sp.、Glyptograptus sp.、Campograptus lobiferus、C. cf. lobiferus、C. cf. obtusus、C.? circularis、Lituigraptus cf. convolutus、Rastrites cf. perfectus、Stimulograptus sedgwickii、Streptograptus sp.和Torquigraptus decipiens。该组合面貌确定其属于志留系兰多维列统埃隆阶上部Lituigraptus convolutus带至Stimulograptus sedgwickii带。这一新材料的发现, 使西藏南部的志留纪地层得以作全球对比。

| Abstract: | Silurian graptolite-bearing strata in Nyalam County are one of the few known sources of Silurian graptolites in southern Xizang (Tibet). Recent graptolite collections from the Shiqipo Formation at Yalai Village, Nyalam County, contain Normalograptus sp., Glyptograptus sp., Campograptus lobiferus, C. cf. lobiferus, C. cf. obtusus, C.? circularis, Lituigraptus cf. convolutus, Rastrites cf. perfectus, Stimulograptus sedgwickii, Streptograptus sp. and Torquigraptus decipiens. This assemblage indicates a late Aeronian (Llandovery) age (Lituigraptus convolutus to Stimu- lograptus sedgwickii biozones). This new finding provides the potential for the correlation of Silurian strata between Xizang (Tibet) and other parts of the world. |
