A contribution to the knowledge of stratigraphic position of magmatic rocks of teschenite association in the Silesian Unit

Vol.20,No.1-2(2013)

Abstract
New results of stratigraphic investigations of the Early Cretaceous sediments of the Hradiště Formation accompanying magmatic rocks of the teschenite association of the Silesian Unit (flysch belt, the Western Carpathians) were made based on noncalcareous dinoflagellate cysts. In view of the dinoflagellate cysts found, the stratigraphic range of the magmatic rocks under study is from the Late Hauterivian to the Late Barremian. It is also possible to assume that the main area of the magmatic activity around Nový Jičín and Příbor is associated with the Late Barremian.
