抽象的。详细的地层记录可追溯到海洋同位素阶段 (MIS) 5b(约 91 kyr),已从普雷斯帕湖(马其顿、阿尔巴尼亚和希腊)的 17.76 m 长岩心 (Co1215) 建立。通过 XRF 扫描、磁化率测量以及沉积物的宏观和微观检查,总共识别出 11 个火山灰层和隐岩层(PT0915-1 至 PT0915-11)。玻璃碎片和/或微浮石碎片的主要元素组成表明,火山灰和隐火山灰源自意大利的爆发性火山活动。八个火山灰层和隐火山灰层与特定火山喷发相关:公元 512 年索马-维苏威火山喷发(距今 1438 年)、索马-维苏威火山 Mercato 喷发(距今 8890 ± 90 年)、Campi Flegrei 的 Tufi Biancastri/LN1-LN2 喷发(距今 14 749 ± 523 年) cal yr BP 和 15 551 ± 621 cal yr BP)、Campi Flegrei 的 SMP1-e/Y-3 喷发(30 000–31 000 cal yr BP)、Campanian Ignimbrite/Y-5 喷发的 Campi Flegrei(39 280 ± 110 cal BP)、伊斯基亚岛的 SMP1-a 事件岛(距今 44 000 年左右)和潘泰莱里亚岛的绿色凝灰岩/Y-6 喷发(距今 45 000 年左右)。一颗火山灰可能是埃特纳火山的火山活动造成的,但也可能代表了大约在 1997 年发生的一次未知喷发。 60 000 卡路里年血压。 Cryptotephras PT0915-6 和 PT0915-10 到目前为止仍未分类,但根据提出的年龄深度模型,它们分别沉积在 35 000 和 48 500 cal yr BP 左右。一些碎石和隐石是首次在巴尔干地区被发现。地层学工作提供了有关火山灰扩散和火山喷发模式的重要信息,可用于对地中海中部地区地理上遥远的古环境和考古档案进行关联和年代测定。此外,地层学工作与放射性碳和电子自旋共振 (ESR) 测年相结合是根据沉积物序列 Co1215 推断古气候重建的先决条件。
Abstract. A detailed tephrostratigraphic record, which dates back to Marine Isotope Stage (MIS) 5b (ca. 91 kyr), has been established from a 17.76 m long core (Co1215) from Lake Prespa (Macedonia, Albania and Greece). A total of eleven tephra and cryptotephra layers (PT0915-1 to PT0915-11) were identified, using XRF scanning, magnetic susceptibility measurements, and macro- and microscopic inspection of the sediments. The major element composition of glass shards and/or micro-pumice fragments indicates that the tephras and cryptotephras originate from the explosive volcanism of Italy. Eight tephra and cryptotephra layers were correlated with specific volcanic eruptions: the AD 512 eruption of Somma-Vesuvius (1438 cal yr BP), the Mercato eruption of Somma-Vesuvius (8890 ± 90 cal yr BP), the Tufi Biancastri/LN1-LN2 eruption of the Campi Flegrei (14 749 ± 523 cal yr BP and 15 551 ± 621 cal yr BP), the SMP1-e/Y-3 eruption of the Campi Flegrei (30 000–31 000 cal yr BP), the Campanian Ignimbrite/Y-5 eruption of the Campi Flegrei (39 280 ± 110 cal yr BP), the SMP1-a event of Ischia Island (around 44 000 cal yr BP) and the Green Tuff/Y-6 eruption of Pantelleria Island (around 45 000 cal yr BP). One tephra could be attributed to the volcanic activity of Mount Etna, but probably represents an unknown eruption at ca. 60 000 cal yr BP. Cryptotephras PT0915-6 and PT0915-10 remain unclassified so far, but according to the presented age-depth model these would have been deposited around 35 000 and 48 500 cal yr BP, respectively. Some of the tephras and cryptotephras are recognised for the first time in the Balkan region. The tephrostratigraphic work provides important information about ash dispersal and explosion patterns of source volcanoes and can be used to correlate and date geographically distant paleoenvironmental and archaeological archives in the central Mediterranean region. Moreover, the tephrostratigraphic work in combination with radiocarbon and electron spin resonance (ESR) dating is a precondition for paleoclimatic reconstructions inferred from the sediment succession Co1215.
