Discovery of the Conodonts in Upper Triassic Bayankalashan Group, Cabanualdo Region, Qinghai Province and Its Significance
-
摘要: 在青藏高原北部卡巴纽尔多湖-错坎巴昂日东湖一带上三叠统巴颜喀拉山群中首次发现牙形石Epigondolella sp.、Metapolygnathus communisti、Metapolygnathus spp.、Metapolygnathus primitius及有孔虫Gaudryina sp.、Jacullella sp.、Verneulinoides maurtii（Terquem）、Gaudryina triassica Trifonova、Ammodiscus sp.等。其中，Epigondolella与Metapolygnathus均为晚三叠世诺利期典型牙形石和常见类型，有孔虫亦显示为晚三叠世常见分子，从而为厘定该套地层时代提供了重要生物依据，对于该地区巴颜喀拉山群形成于早三叠世和中三叠世早期的观点有待于重新审视。Abstract: Conodonts (Epigondolella sp., Metapolygnathus communisti, Metapolygnathus spp., Metapolygnathus primitius) and foraminifers (Gaudryina sp., Jacullella sp., Verneulinoides maurtii (Terquem), Gaudryina triassica Trifonova, Ammodiscus sp.) are firstly discovered in Upper Triassic Bayankalashan Group, Cabanualdo Lake-Khampat Kardong Lake region, northern Qinghai-Tibet Plateau. In which, Epigondolella and Metapolygnathus are typical and vary common conodonts in Norian Stage of Late Triassic Period. The foraminifers are also show as common elements of Late Triassic Period. Thus, on the basis of these important biological data, the strata age in this area can be determined. The traditional opinion of Bayankalashan Group Group formed from Early Triassic to Middle Triassic in this area needs to be reviewed.
