| 摘 要： | 简要介绍国际泥盆系各阶界线定义、界线层型,以及目前进行的国际泥盆系埃姆斯阶、吉维阶、弗拉斯阶和法门阶亚阶划分的情况,并讨论了中国区域性阶与国际性阶之间的关系:除了埃姆斯阶和法门阶在华南分别进一步细分为郁江阶和四排阶以及锡矿山阶和邵东阶等外,那高岭阶、应堂阶、东岗岭阶和佘田桥阶大致分别相当于布拉格阶、艾费尔阶、吉维阶和弗拉斯阶;今后需加强对上述几个中国区域性阶底界确切时代的研究。国际泥盆系中各亚阶在我国大体可以应用,但吉维阶中亚阶-上亚阶、弗拉斯阶下亚阶-中亚阶的分界及最上法门亚阶的底界在华南台地相区岩石地层上不易划分。

| Abstract: | Devonian GSSPs (Global Stratotype Sections and Points) and the status of the international discussions on the Devonian substage divisions are introduced. Then correlation of the Chinese Devonian regional Stages with the international Stages is discussed. In South China, the Emsian can be correlated with both of the Yujiangian and Sipaian Stages; and the Famennian includes the Xikuangshanian, an unnamed (to be established), and the Shaodongian Stages. The Nagaolingian, Yingtangian, Dongganglingian, and Shetianqiaoan Stages can be roughly corresponded to the Pragian, Eifelian, Givetian, and Frasnian respectively, although exact ages of the base of the above Chinese Stages need further study. Possible application of the internationally discussed substages in South China is also discussed: Middle/Upper Givetian, Lower/Middle Frasnian, Upper/Uppermost Famennian boundaries do not seem to be easily determined in the platform facies of South China. |
