摘要/Abstract

摘要： 描述新疆库鲁克塔格地区南部却尔却克山白云岗组的牙形石,计 14 属 19 种和 3 未定种,分为 6 个牙形石带,从下至上依次为：Proconodontusposterocostatus 带、Proconodontusmuelleri 带、Eoconodontusnotchpeakensis 带、Cordylodusproavus 带、Cordyloduslindstromi 带和 Cordylodusangulatus带。根据牙形石带,初步划分了寒武系与奥陶系界线。

关键词: 新疆, 库鲁克塔格, 牙形石, 晚寒武世, 早奥陶世

Abstract: This paper presents the conodonts collected from Baiyungang formation in Queerqueke mountain, southern Kuruktag area in Xinjiang, consisting of 19 species and 3 undetermined ones, belonging to 14 genuses. They are classified into 6 conodont zones from bottom to top, such as Proconodontus posterocostatus zone, Proconodontus muelleri zone, Eoconodontus notchpeakensis zone, Cordylodus proavus zone, Cordylodus lindstromi zone and Cordylodus angulatus zone. Based on these conodont zones, the Cambrian-Ordovician boundary in this area is preliminarily determined.

Key words: Xinjiang, Kuruktag, conodont, Late Cambrian, Early Ordovician
