在这里，我们提出了一个火山灰地层记录（核心钴1202）恢复奥赫里德湖（马其顿共和国和阿尔巴尼亚）的东北部，可追溯到海洋同位素阶段（MIS）6。在整个14.94 m长的沉积物序列中，共识别出10个含有火山碎屑的层位（OT 0702 - 1至OT 0702 - 10）。肉眼检查可见四层火山灰层（OT 0702 - 4、OT 0702 - 6、OT 0702 - 8和OT 0702 - 9），其余6个为隐晶岩（OT 0702 - 1、OT 0702 - 2、OT 0702 - 3、OT 0702 - 5、OT 0702 - 7和OT 0702 - 10），根据K、Zr和Sr强度峰值、磁化率测量值，和沉淀物的洗涤和筛分。火山灰层和隐火山灰的玻璃碎片进行了分析，其主要元素组成，并与意大利火山爆发。火山灰层和隐火山灰的地层学和主要元素组成允许将OT 0702 - 1与索玛-维苏威火山的AD 472或AD 512喷发、OT 0702 - 2与埃特纳火山的FL喷发、OT 0702 - 3与索玛-维苏威火山的Mercato喷发、OT 0702 - 4与Campi Flegrei破火山口的SMP 1-e/Y-3喷发相关联，OT 0702 - 5到Codola喷发（Somma‐Vesuvius或Campi Flegrei），OT 0702 ‐6至Campi Flegrei破火山口的Campanian火山灰岩/Y‐5，OT 0702 ‐7至Pantelleria岛的绿色凝灰岩/Y‐6喷发，OT 0702 ‐8至X‐5喷发可能源自Campi Flegrei破火山口，OT 0702 - 9与坎帕尼亚起源的X-6喷发有关，OT 0702 - 10与潘泰莱里亚岛的P-11喷发有关。这些火山灰层和母火山喷发的相当著名的年龄提供了这些火山灰的分散和沉积的新数据，此外，允许建立一个年代框架的核心Co 1202的主要沉积变化的第一个解释。版权所有© 2009约翰威利父子有限公司。
Here we present a tephrostratigraphic record (core Co1202) recovered from the northeastern part of Lake Ohrid (Republics of Macedonia and Albania) reaching back to Marine Isotope Stage (MIS) 6. Overall ten horizons (OT0702‐1 to OT0702‐10) containing volcanic tephra have been recognised throughout the 14.94 m long sediment succession. Four tephra layers were visible at macroscopic inspection (OT0702‐4, OT0702‐6, OT0702‐8 and OT0702‐9), while the remaining six are cryptotephras (OT0702‐1, OT0702‐2, OT0702‐3, OT0702‐5, OT0702‐7 and OT0702‐10) identified from peaks in K, Zr and Sr intensities, magnetic susceptibility measurements, and washing and sieving of the sediments. Glass shards of tephra layers and cryptotephras were analysed with respect to their major element composition, and correlated to explosive eruptions of Italian volcanoes. The stratigraphy and the major element composition of tephra layers and cryptotephras allowed the correlation of OT0702‐1 to AD 472 or AD 512 eruptions of Somma‐Vesuvius, OT0702‐2 to the FL eruption of Mount Etna, OT0702‐3 to the Mercato from Somma‐Vesuvius, OT0702‐4 to SMP1‐e/Y‐3 eruption from the Campi Flegrei caldera, OT0702‐5 to the Codola eruption (Somma‐Vesuvius or Campi Flegrei), OT0702‐6 to the Campanian Ignimbrite/Y‐5 from the Campi Flegrei caldera, OT0702‐7 to the Green Tuff/Y‐6 eruption from Pantelleria Island, OT0702‐8 to the X‐5 eruption probably originating from the Campi Flegrei caldera, OT0702‐9 to the X‐6 eruption of generic Campanian origin, and OT0702‐10 to the P‐11 eruption from Pantelleria Island. The fairly well‐known ages of these tephra layers and parent eruptions provide new data on the dispersal and deposition of these tephras and, furthermore, allow the establishment of a chronological framework for core Co1202 for a first interpretation of major sedimentological changes.
