Uncalibrated radiocarbon age of sample material from Marienberg, Brandenburg a.d. H.@en

A 14C-Dated pollen diagram of the Marienberg in the old town of Brandenburg a. d. Havel shows the history of vegetation at this site for the entire Holocene. Since it is a small pollen archive, it offers statements of local significance. It shows on the one hand the development of the forest vegetation at Marienberg, on the other hand the formation of a wet biotope from a pond with a water depth of several meters to a fen and finally to a pond, which was strongly eutrophicated especially in the Middle Ages and in modern times. The prehistoric and early historical settlement is only weakly reflected in the pollen findings. Of special interest are findings of walnut and wine pollen, which can be connected to the Medieval monastary Marienstift, which was an important place of pilgrimage.

哈弗尔河畔勃兰登堡老城马里恩贝格遗址的14C定年孢粉图（pollen diagram），完整展现了该遗址全新世（Holocene）以来的植被演化历史。由于该孢粉记录（pollen archive）规模有限，其研究结论仅具备局域参考价值。该图谱一方面揭示了马里恩贝格地区森林植被的演替进程，另一方面展现了一处湿地生境（wet biotope）的演化路径：初始为水深数米的池塘，逐步演变为沼泽（fen），最终再度形成池塘——该水体在中世纪至近现代时期曾遭受严重富营养化污染。史前及早期历史时期的人类聚落活动仅在孢粉记录中得到微弱反映。尤为值得关注的是记录中检出的胡桃与葡萄花粉，其来源可关联至中世纪时期作为重要朝圣圣地的马里恩修道院（Marienstift）。
