The central part of the Křivoklát-Rokycany Furongian volcanic complex was studied. Volcanic suite consists of lower (andesite, basalt lavas) and upper (rhyolite and dacite lavas and ignimbrites) successions resting on Cambrian sediments. Most ignimbrites reveal agglomerate facies, eutaxitic patterns are rare. These deposits represent the lower parts of pyroclastic flows in proximal position.
