摘要: 本文首次对新疆巴楚小海子岩关期牙形类7属11种进行了研究,分析和论证其生物地层意义,提出泥盆—石炭系界线划在Siphonodella出现稍低位置(巴楚组中段底),并确认原卡拉沙依组亦应为岩关期地层,从而述及岩关阶内部事件在塔北的新发现——巴楚运动。

Abstract: This paper studies conodonts (7 genera with 11 species),analysing and discussing its biostratigraphic significance in Yan Guan period at Xiaohaizi,BaChu of XinJiang. The Devonian-Carboniferous boundary is drawn at the position slightly lower than that where iphonodella occurs (the base of middle member of BaChu formation ).It is aslo determined that the original Kalasay formation is actually Yan Guan period deposite, BaChu movement diseribed as a new discovery of interior events of Yan Guan stage in TaBei.

Key words: Yan Guan period, conodonts, animal group, BaChu of XinJiang
