Photo: Sweet drops of Tokaj Mts. (HU) The field trip covers an area which locates in the heart of the Tertiary-Quaternary intermediate-acidic volcanic arc of the Carpathians. The volcanic landscapes of the Tokaj Mts. and Slanské vrchy Mts. units are built up by medium to high K calk-alkaline volcanic rocks from basaltic andesite to rhyolite of 10-13 Ma age. The area is unique by the occurrence of voluminous acidic rocks and the trip targets the perlite quarry at Pálháza which nicely exposes a rhyolitic cryptodome-dome complex and related pyroclastic flows. In the quarry at Erdőbénye, a complete section of a dacitic laccolith rich in mineral-bearing vugs will also be visited. Exposures of ignimbrite will be presented at several localities with obsidian at Stredá nad Bodrogom and clinoptilolite-mordenite mineralization near Mád. Volcanism was associated with intense hydrothernal activity and due to the relatively low erosion level of the area, shallow levels of low sulphidation type epithermal systems are also preserved. Shallow zones of those systems are the paleo-hotspring fed lacustrine silica deposits, and steam-heated alteration zones with alunite and kaolinite in the area of Mád. Hydrothermal activity also produced a high quality illite deposit which will be visited underground at Füzérradvány. One of the merit of the trip is the only precious opal deposit in Europe at Dubník near Červenica. The trip also aims to introduce the cultural heritage of the area by sightseeing tours in Sárospatak and Košice and a true renaissance style dinner in the old castle at Sárospatak. The area is the homeland of the Tokaj wine and participants will get a good training to recognize varieties of this famous wine by visits to cellars. Those visits will also be supported by traditional Hungarian and Slovakian dinners.
