crevice-type caves, gravitational slope deformations, pseudokarst

Crevice-type rockslide caves are developed in a different types of rocks (sediments, granites, limestones) where some kinds of slope deformations are established. The rockslide caves originate by the process of fissure propagation within the landslide body. The different types of mechanisms are enforced such as toppling, spreading and rotational movement. Each of them is accompanied by the genesis of typical shapes of underground crevices. We investigated some of the typical localities with occurrence of landslides and crevice-type caves: e.g. Crimean mountains (limestones), Outer Western Carpathians (flysh rocks - sandstones, shales; limestones) by several methods: electrical resistivity tomography, microstructural measuring, speleological and surface mapping, digital elevation model and cave maps comparison.
