摘要

佩加蒙微区(西基耶岛)在全新世经历了几个增强的地貌动力学阶段。然而,在希腊化和罗马帝国时期之间的转变过程中,地方-区域人类活动与超区域气候波动的作用仍在讨论中。本文对deliktai流域冲积扇的5个沉积物剖面进行了分析,并进行了放射性碳定年,以提供覆盖全新世的沉积学记录。我们的研究结果显示了泥沙动力学变化的七个阶段。全新世5个旋回的粗粒和细粒扇状沉积覆盖了Çaylak溪的古河道沉积和中全新世向山前淤积的接收格伊克利河洪泛平原沉积。古土壤表明,德利克塔伊扇和格伊克利洪泛平原的景观至少在约4 ~ 3.4 cal ka BP左右稳定下来。这些古土壤再次被扇状沉积物掩埋,标志着晚全新世加速地貌动力学的第一阶段。人类活动的局部发生和气候快速变化的区域中全新世干旱化都发挥了作用。据推测,德利克塔伊地区和佩加蒙微区在希腊-罗马转变期间考古遗址数量的增加和人类对环境的高压力导致了过去2.5 ka期间地貌动力学活动的增加。然而,这一点在我们的记录中不太明显。我们的研究强调了气候系统和城乡文化历史对景观发展的重要性,并提出了地中海东部地区不同的地貌动力学对区域尺度变化的潜在响应。

Holocene geomorphodynamics of a rural catchment in the Pergamon micro-region (eastern Mediterranean)
The Pergamon micro-region (western Türkiye) has experienced several phases of increased geomorphodynamics during the Holocene. However, the role of local–regional human activities during a transformation between Hellenism and the Roman Imperial period and supra-regional climate fluctuations is still under discussion. Five sediment profiles from the alluvial fan of the rural Deliktaş catchment are analyzed and radiocarbon-dated to provide a sedimentological record covering the Holocene. Our results indicate seven phases of changing sediment dynamics. Five Holocene cycles of coarse- and fine-textured fan sediment deposition covered the paleochannel deposits of the Çaylak creek, and the floodplain sediments of the receiving Geyikli river which aggraded toward the piedmont during the Mid-Holocene. The landscape became stable on the Deliktaş fan and Geyikli floodplain at least ca. 4–3.4 cal ka BP as indicated by paleosols. These paleosols were again buried by fan sediments marking the first phase of accelerated geomorphodynamics during the Late Holocene. Both the local onset of human activities and the regional Mid-Holocene aridization with rapid climate changes play a role. The increased number of archeological sites and high human pressure on the environment during the Hellenistic–Roman transformation in the Deliktaş area and Pergamon micro-region were hypothesized to contribute to a phase of increased geomorphodynamic activity during the last 2.5 ka. This, however, is less apparent in our record. Our study emphasizes the importance of both, the climatic system and rural-urban cultural history, on landscape development, suggesting potential responses of locally diverse geomorphodynamics on regional-scale transformation in the eastern Mediterranean.

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.
