[vc_row][vc_column width=”2\/3″][vc_column_text]Contrary to popular opinion about the inactive status of the Sudetes, the evolution of the Nied\u017awiedzia Cave in Kletno was controlled by alpine tectonic movements. Dr. Jacek Szczygie\u0142, together with a team from the universities of Wroc\u0142aw and Vienna, published in the journal Geomoprhology<\/i> the results of detailed geological mapping and structural analysis of Nied\u017awiedzia Cave, provides new insights into proto-conduit formation in karstic drainage. The resulting data has been used to build a detailed 3D model of the marble lens hosting the cave, allowing us to define the primary structural guidance trends. It was noted that karst development was controlled by vertical faults, with a secondary role for foliation. Based on cave micromovements and other neotectonic indicators, as well as the relationship between structural discontinuities and topography, it was deduced that structural discontinuities became favorable for karst development under alpine stress conditions, with little or no influence of massif relaxation. The vertical, level-like pattern of Nied\u017awiedzia Cave was further controlled by the incising of the Kle\u015bnica River.<\/p>\n
