摘要

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。

Foraminifera in the glacial erratic rock Heiligenhafener Kieselgestein of northern Germany

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.

期刊介绍： The Journal of Micropalaeontology (JM) is an established international journal covering all aspects of microfossils and their application to both applied studies and basic research. In particular we welcome submissions relating to microfossils and their application to palaeoceanography, palaeoclimatology, palaeobiology, evolution, taxonomy, environmental change and molecular phylogeny. Owned by The Micropalaeontological Society, the scope of the journal is broad, demonstrating the application of microfossils to solving broad geoscience issues.
