Abstract

Relics of two Miocene streams deposited mostly on Cambrian volcanic rocks in Křivoklát area were recognized. The main Miocene stream drained from S to N, while the narrow tributary incised in W-E direction. Pebbles of both streams' sediments are formed by quartz, silicite, conglomerate. Relics of the main stream frequently contain pebbles of Cambrian volcanic rocks. Ilmenite is the most common heavy mineral of Miocene sediments.
