Ropomatečné horniny ve spodní křídě v oblasti Moravskoslezských Beskyd

Abstract

Moravo–Silesian Beskydy Mountains presents broken upland outbranching in the northeast of Moravia along the Slovakian border. With their geological structure they belong to the Outer Western Carpathian Mountains. The Outer Western Carpathians are formed mostly by Cretaceous and Paleogene marine clastics. They are richly formed by claystones, siltstones and sandstones. From the 19. century the area of the Outer Western Carpathians is allowed to be oil and gas area. In the study area there are deposits rich on the organic carbone material (amount of the organic carbone material even 3,5%), mostly darkly coloured claystones and siltstones, which settled in the anoxic conditions. These deposits are situated in the highest amount in the Silesian unit. Oil character of sediments was studied on the basis of structure of the organic material and degree of their transformation.
