| Povzetek: | In the wider Idrija area in western Slovenia, several large plains formed along the thrusts within the dolomite and at the contact of dolomite and limestone. The purpose of this paper is to present the detailed structural-geological background of one such plain, namely the Zadlog plain, and based on these findings, to provide new starting points for analyzing the genetic conditions of other karst poljes in Notranjska. The Zadloško polje was formed in a wider near-fault crushed zone at the contact of two structural units within the Upper Triassic Norian-Rhaetian dolomite, with the thrust crossing the polje in its central part. The initially lowered area at the thrust represented a morphological basis, and the crushed zones in the dolomite played a hydrological retention role inducing the stagnation of surface water and, as a result, the formation of the karst polje. Younger fault tectonics then established efficient drainage of surface water and the erosion of sediments to the karst underground. Besdies this, slope equilibration leads us to conclude that the karst polje capability of hydrologic retention is recently decreased. The example of Zadloško polje shows that the thrust structures and associated hydrological conditions are the key elements for the formation of karst poljes in the dissected karst surface. Further detailed structural-geological mapping will reveal whether similar structural-geological conditions are the basis for the formation of other karst poljes in the region. |
