Edited sentence: According to some authors, Permian volcanism in Hronic has polyphase linear character.Among the Permian rock the Ipoltica Group of the Hronic nappe is best known.Basic volcanism is recognized in the Carboniferous and Permian rock.Cretaceous těšínites (sub-volcanic alcalic gabbro) were found in the Slesian zone of the Flysch Belt.. Remnants of destructed ophiolites with N-MORB basalts in upper part are present in the rock of the Meliatic...It is characteristic by synsedimentary dacite to andesite volcanism in lower part and andesitic-basalts close to the Tholeitic type in the upper part.Large volume of volcanic rock, considered as product of stratovolcanos, significantly changed by metamorphism are present in the Gemeric.Lower part of the group is called the Malužiná Formation.Mesozoic volcanic processes are more distinct and known from all zones of the Western Carpathians.Nodules of hydrotermal agate are common in the cavities of these rock, widely known as the melaphyrs.Picrites are known around Banská Bystrica.Significat volcanic activity took place in the Lower Paleozoic in the Malé Karpaty Mts.The Jurassic-Cretaceous tectonic structure was later changed by various types of the overstep complexes: the Central Carpathian Paleogene Basin, Buda Paleogene Basin, Vienna Basin (Neogene, pull-apart type), Pannonian Basin (or the Danube Basin) and the volcanic complexes: Neogene volcanics of Carpathians (or just Neovolcanis).The oldest forms of volcanism, which affected the area of the Western Carpathians are hardly recognized because of later tectonic processes and a destruction by erosion.There are Triassic effusives in the rock of Fatric and Hronic of the Malá Fatra Mts.and Nízke Tatry Mts.where the relicts are seen in the rock of the Pernek Group with typical basic volcanism
