Volcanic Rock Structures as Indicators of Dangerous Environmental Impact: The Late Cenozoic Volcanics in the Caucasus

摘要

The structure features of lavas and ignimbrites indicate a high role of volatiles in their formation and a rapid release of volatiles from cooling melt. This poses a high risk for the environment. For this reason it is important to study the structures of resulting volcanic rocks for predicting the degree of hazard in the event of a future resumption of volcanic activity.
