Geological structure of karst stratigraphical windows at Škocjan Caves, Slovenia

Abstract Within the UNESCO Škocjan Caves, detailed geological structural mapping of cave passages and surface above revealed interesting structural-lithological characteristics two major collapse dolines, Velika Dolina Mala Dolina. As a result karst processes effects formation older—stratigraphically lower—carbonates Sežana Formation (K 2 2−4 ) crop out at surface, underlying rocks younger Lipica 4−5 ). Here we do not recognize windows only in geomorphological sense but, acknowledging characteristic lithostratigraphical relationships involved, suggest use new expression “karst stratigraphical window”. Recognizing that karstic areas contain numerous dolines other doline types, presume many more examples exist, these are distinct from tectonic windows. Our study showed importance during making maps areas, it is essential to examine features such as which may be identified Therefore, providing additional data, information about stratigraphic boundaries structure, without abundance outcropping resulting inclusive comprehensive maps.
