项目摘要
The eastern Mediterranean is highly sensitive to abrupt climatic changes due to its location at the confluence of distinct atmospheric circulations. Past environmental records offer insights into the climatic drivers and environmental responses. However, chronological uncertainties present challenges in fully understanding potential regional climatic (a)synchronies. The method of using tephra (volcanic ash), both visible and non-visible (cryptotephra), can be a powerful chronological tool to overcome these problems. By geochemically characterising volcanic sources and their eruptions, tephra correlations can offer precise dating and synchronous time markers (isochrones), enabling the linking and dating of records across regions. The proposed research of TephroBridge aims to establish a detailed tephrostratigraphy for one such important volcanic centre, the Eastern Anatolian Volcanic Province (EAVP). The volcanoes of Nemrut and Süphan are significant sources of tephra in the region, found in numerous palaeoclimatic and archaeological records, but a comprehensive tephrostratigraphy is still lacking. The study plans to geochemically characterise the tephra layers from Lake Van's Ahlat Ridge core (5034-2) using techniques like electron probe micro-analysis (EPMA) and LA-ICP-MS. Petrographic identification, morphological descriptions, and thin section analysis will further characterise the tephra layers. The research aims to correlate these newly geochemically analysed tephra layers, the major, minor, and trace element compositions, with cryptotephra layers found in the Dead Sea record and other important palaeoclimatic and archaeological records in the region. The study's future success is demonstrated so far by the TephroMed project, which correlated cryptotephra layers from the Dead Sea to Lake Van's tephra layers, refining the Levant's chronology and providing insights into past climatic variability. Overall, this research project will establish a comprehensive tephrostratigraphic framework for the EAVP. This will enable improved synchronisation of regional records using tephra layers to enhance insights into past climatic responses in the eastern Mediterranean, bridging the gap in knowledge of the current Mediterranean chronology.
东地中海由于位于不同大气环流的交汇处,对气候突变非常敏感。过去的环境记录提供了对气候驱动因素和环境反应的见解。然而,年代的不确定性在充分理解潜在的区域气候(a)同步性方面提出了挑战。使用火山灰(火山灰)的方法,无论是可见的还是不可见的(隐火山灰),都可以成为克服这些问题的有力的年代学工具。通过对火山源及其喷发的地球化学特征进行描述,火山灰相关性可以提供精确的测年和同步时间标记(等时线),从而使跨区域记录的联系和测年成为可能。TephroBridge的拟议研究旨在为这样一个重要的火山中心,东安纳托利亚火山省(EAVP)建立详细的火山灰地层学。内姆鲁特火山和苏潘火山是该地区火山灰的重要来源,在许多古气候和考古记录中发现,但仍然缺乏全面的火山灰地层学。该研究计划使用电子探针显微分析(EPMA)和LA-ICP-MS等技术对来自货车湖阿赫拉特海岭岩心(5034-2)的火山灰层进行地球化学分析。岩相鉴定、形态描述和薄片分析将进一步对火山灰层进行分析。该研究旨在将这些新的地球化学分析的火山灰层,主要,次要和微量元素成分与死海记录和该地区其他重要的古气候和考古记录中发现的隐火山灰层相关联。到目前为止,这项研究的未来成功已经被TephroMed项目所证明,该项目将死海的隐火山灰层与货车湖的火山灰层相关联,完善了黎凡特的年表,并提供了对过去气候变化的见解。总体而言,本研究项目将建立一个综合的火山灰地层框架的EAVP。这将使区域记录使用火山灰层,以提高对过去的气候反应在地中海东部的见解,弥合差距在目前的地中海年表知识的同步。
