Abstract

This paper presents a summary of work done over a period of more than five years. The object of this work was the investigation of rock jointing and other microtectonic phenomena in the Carpathian Flysch and in the SE border region of the Czech Massif. Two types of macro-joints, i.e. (i) bedding joints and (2) joint zones have been established. Attention has been paid primarily to joint zones that represent an important element in the regional structural pattern. Bedding joints and joint zones distributed over the studied area exhibit a variable density. The identification of joint zones grouped in sets can contribute to the knowledge of the tectonics over the entire area studied and, on the basis of the results achieved in the mapped region, the tectonics in other regions can be solved. Joint zones indicate the tectonic stresses to which the rocks were subjected. The study has revealed close tectonic relations between the Carpathian system and the Czech Massif.
