Abstract

In this study the foraminifera of the glacial erratic Heiligenhafener Kieselgestein (HKG) consisting of siliceous sandstones are documented for the first time. The glacial erratics in northern Germany were deposited during the Pleistocene. The age of the HKG sandstone is indicated as Eocene from 49.6 Ma to 47.8 Ma. The lower limit is given by the first occurrence of the planktonic foraminifera Pseudohastigerina micra (Cole 1927). The upper limit is derived from previous studies of the Eocene succession of Northern Germany based on benthic foraminiferal faunas. The HKG fauna indicates a boreal, fully marine environment characteristic for a water depth between 50 m and 80 m.

德国北部Heiligenhafener-Kieselgestein冰川不稳定岩石中的有孔虫

在本研究中，首次记录了由硅质砂岩组成的冰川不稳定海利根哈芬-基塞尔格斯坦（HKG）的有孔虫。德国北部的冰川遗迹是在更新世沉积的。HKG砂岩的年龄为始新世，从49.6 Ma到47.8 Ma。下限由浮游有孔虫Pseudohastigerina micra的首次出现给出（Cole 1927）。上限来源于先前基于底栖有孔虫动物群对德国北部始新世演替的研究。HKG动物群表明，水深在50米到80米之间的北方完全海洋环境特征。

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.
