| 摘 要： | 内蒙古达茂旗巴特敖包地区的西别河剖面是西别河组的建组剖面,时代争议较大.西别河剖面的牙形刺研究表明:西别河剖面的下、中部应归入上志留亚系(Ludlow to Pridoli),发现了可与Ludlow统标准牙形刺带Ozarkodina crispa对比的牙形刺Ozarkodina uncrispa.剖面的上部为下泥盆统阿鲁共组,时代为Lochkovian阶,发现了下泥盆统Lochkovian阶特有的牙形刺属Ancyrodelloides,Lanea.西别河剖面不宜作西别河组的标准剖面,包尔汉图剖面可作为西别河组的标准剖面.

| Abstract: | The Xibiehe section, as the original standard of the Xibiehe Formation, is located at the Bateaobao area in Darhan Mumingan Joint Banner, Inner Mongolia.Its age has been much debated. The conodont study clearly shows that the lower and middle part of the Xibiehe section should be assigned to the Late Silurian Xibiehe Formation(Ludlow to Pridoli) based on the finding of Ozarkodina uncrispa which can correlate with the lower part of Ozarkodina crispa Zone.The upper part of this section called the Alugong Formation, belongs to the Lochkovian of early Devonian, because typical Lochkovian conodont genus Ancyrodelloides and Lanea have been found. The Xibiehe section is not suitable for being the standard section of the Xibiehe Formation, however, the Baoerhantu section can be used as a standard section of the Xibiehe Formation. |
