摘要：Tokaj Mountains (TM) is well known for the occurrence of the Carpathian Obsidian. This paper presents a
general stratigraphy, geochronology and lithology framework for Miocene volcanic successions associated with
obsidian formation in the area. Specific localities were chosen to show an accurate description of the geological
settings. The primary occurrences are related to deposits of the Sarmatian – Lower Pannonian silicic effusive
and explosive volcanism in the area of Szerencs and Erdőbénye - Erdőhorváti Caldera. The lava bodies are flow
or dome like in morphology and were built-up during the several phases between 12.8±0.5 and 10.6±0.5 Ma.
The Lebuj and Rókabérc localities contain obsidian marekanite (0,5-3 cm) nested in banded perlite that
developed in the medial and basal, glassy part of the flow sequences. The pumice rich volcanoclastic deposits
also contains fresh, angular obsidian lapilli (
