Late Miocene volcanic activity in the České středohoří Mountains (Ohře/Eger Graben, Northern Bohemia)

Original language description

First occurrences of superficial bodies of Late Miocene volcanic activity were found in the w. part of the České středohoří Volcanic Complex. Their K-Ar ages (9.59, 9.61 and 11.36 Ma) correspond to the age of alkaline basaltic rocks of the youngest knownIntrusive System of this area. These bodies are represented by superficial products: two scoria cones with remnants of lava flows and one exclusive lava flow produced from a lava cone. Their primitive (basanitic) chemical composition, Sr (0.70347 ? 0.70361) and Nd (0.51279 ? 0,51284) isotope ratios are similar to the products of the first and third volcanic formation of the CSVC. The proved existence of superficial products, together with clear superposition relations to sedimentary formations and thechemical character of the youngest magmas support the stratigraphic scheme of volcanic activity in the České středohoří Mts. Eruptive style of the youngest formation volcanoes was purely magmatic (Strombolian) with no phreatic influence.
