爱琴海南部圣托里尼火山青铜时代（米诺斯文明）猛烈喷发所产生的火山灰扩散一直是许多研究的主题1-6。取自土耳其西部一个小山湖的沉积岩芯含有一层米诺斯火山喷发的火山灰。圣托里尼岛的起源是根据折射率、主要玻璃化学成分和地层位置确定的。该湖位于公认的火山灰散布区以北。该矿床提供了米诺斯火山灰散布到圣托里尼岛东北部的证据，并暗示小亚细亚西海岸一定经历了青铜时代喷发造成的大量火山灰沉降物。此前尚未在土耳其遗址中发现过米诺斯火山灰。
Dispersal of volcanic ash from the violent Bronze Age (Minoan) eruption of the Santorini volcano in the southern Aegean has been the subject of much research1–6. A sediment core taken from a small mountain lake in western Turkey contains a layer of tephra from the Minoan eruption. The Santorini origin is established by refractive index, major glass chemistry, and stratigraphic position. The lake is located north of the recognized dispersal area for the tephra. This deposit provides evidence for dispersal of the Minoan tephra well to the northeast of Santorini, and implies that the west coast of Asia Minor must have experienced heavy tephra fallout from the Bronze Age eruption. The Minoan tephra has not previously been identified from sites in Turkey.
