Abstract

Abstract The boundary between the Devonian and the Carboniferous has been drawn using ammonoids, conodonts and miospores, while geochemical data have only rarely been used. The sampling of eight sections (Aprath, Apricke, Effenberg, Wocklum, Stockum, Drewer WJ, Drewer WA, Marsberg) at the northern margin of the Rhenish Mountains demonstrates the potential of the isotope ratio of organic carbon to regionally correlate sections in different facies areas. With the help of the carbon isotopes, a distinct stratigraphic succession is documented, which is characterised by several positive and negative excursions; this succession was recorded in all examined sections. The carbon isotopes can therefore make a significant contribution to the stratigraphic subdivision of sections and complement the biostratigraphic methods.

莱茵山脉泥盆系—石炭系界线剖面有机碳同位素地层学研究

泥盆纪与石炭系界线的划分主要是利用菊石、牙形刺和微孢子进行的，而地球化学资料的应用却很少。通过对莱因尼山脉北缘8个剖面(Aprath、Apricke、Effenberg、Wocklum、Stockum、Drewer WJ、Drewer WA、Marsberg)的采样，揭示了有机碳同位素比值在不同相区区域对应剖面上的潜力。在碳同位素的帮助下，记录了一个明显的地层演替，其特征是多次正偏移和负偏移;这种演替在所有被检查的切片中都有记录。因此，碳同位素可以对剖面的地层细分做出重要贡献，并补充生物地层方法。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
