Lower Cambrian siliciclastic sediments in Southern Moravia(Czech Republic) and their paleogeographical constraints

Abstract

Petrological, sedimentological and ichnological studies of cores from the měnin-1 borehole revealed episodic shallow marine influence in the terrestrial clastics unerlying the Devonian clastic and carbonate rocks. The organic-walled, acid-resistnat microfossils have been recovered from bioturbated beds and have allowed us to determinate the age as the earliest Cambrian.
