Located on the edge of the Geopark lies the Lončarski vis Geosite―in the middle of an active quarry. It offers a good look on huge quantities of 'andesite'―a dark grey volcanic rock that formed when lava cools on the Earth's surface, usually near subduction zones. Andesite is a fine -grained rock that has tiny crystals of minerals like 'plagioclase' and 'pyroxene', giving it a uniquely speckled look. These volcanic rocks were created in the Miocene due to volcanic activities that happend simultaneously to the creation of the Pannonian Basin, so these rocks date back about 20 million years.
