Tefrochronology – Dating with the Help of Volcanic Eruptions
How can scientists precisely determine the age of sediments, lakes, or archaeological sites even when classical methods fail? The answer often lies in — volcanoes.
In the lecture “Tefrochronology – Dating with the Help of Volcanic Eruptions”, Dr. Ivan Razum, Museum Advisor at the Croatian Natural History Museum, will introduce a fascinating scientific method in which layers of volcanic ash (tephra) are used as precise time markers in geological, paleoclimatic, and archaeological research.
Explosive volcanic eruptions leave traces that can be found hundreds of kilometers away from the volcano itself. Since each eruption is chemically and mineralogically unique, its “signature” can be identified in sediment layers and linked to a specific event in the past. Thanks to tephrochronology, it is possible to synchronize natural processes across large spatial scales and accurately reconstruct environmental and climate changes through time.
The lecture is part of the accompanying discursive program for the exhibition “Microworlds – Nature Revealed Through the Lens of the Electron Microscope,” which reveals hidden structures of nature and the modern scientific methods used to study them.
