Hotový, Jan ; Křížek, Marek (advisor) ; Dlabáčková, Tereza (referee)
This paper deals with a topic of blockfields in southern part of the Brdy Mountains. The aim of this work is to describe an origin of the block fields generally, characterise their spatial distribution, morphometric and structure features, including their specific thermal regime. Another task is to characterise and classify the block fields in the southern part of Brdy Mts and compare them with the similar accumulations described in literature. 30 block fields were identified in this area. Morphometric analysis based on digital elevation model revealed that block fields in the southern part of Brdy Mts are sized roughly from 200 to 5 500 m2 and occur mostly at 725 - 750 m a. s. l. on steep or very steep slopes with a prevailing southern- -west and west exposure. An additional exploration of a bedrock confirmed that block fields here consist of conglomerate and silicite rocks. The results provide information about paleoclimate of Brdy Mts and their surroundings. Key words: block fields, Brdy Mountains, frost weathering, morphometric characteristics
