Abstract

The geomorphological rock value is one of the basic terms used in the geomorphological analysis of the territory. It is defined as the resistance of rocks to the action of exogenous geomorphological factors. In the classic separation of degrees of resistance, the shortcoming is that the individual degrees of rock resistance are not separated on an exact basis. This problem could be eliminated by the use of the Schmidt hammer test, which can be used to measure the hardness of rocks and thus their potential geomorphological value. This contribution presents the first results of such measurements in the karst area of Slovakia, using the example of the Miglinc Valley on the Jasovská plateau in the Slovak karst. It follows that in the given area there are rocks with two levels of resistance, namely level 2 - strong resistance and level 3 - moderate resistance according to Selby (1980). These results are preliminary and need to be further refined and extended to a larger area. However, it turns out that the Schmidt hammer test is a suitable tool for determining the geomorphological value of rocks even in karst areas.
