Znaczenie karbonu dolnego Gór Kaczawskich dla budowy i rozwoju Sudetów Zachodnich
Abstract
SIGNIFICANCE OF THE LOWER CARBONIFEROUS IN THE KACZAWA MOUNTAINS FOR STRUCTURE AND DEVELOPMENT OF THE WESTERN SUDETY MOUNTAINS
Summary
The lower stage of the Kaczawskie Mountains which was supposed to contain the Cambrian-Silurian series was considered to the sixties, to be of Caledonian. Followers of that opinion hoped detrital materials of epimetamorphic rocks in the Tournai breccia and conglomerates of the Middle Sudetic synclinorium originated from the Kaczawskie Mountains and also from the Kaczawa Nappes having trusted upon the Karkonosze - Izery block.
The Domanów dislocations, which recently separates the Kaczawa series from the Świebodzice structure and the Middle Sudetic synclinorium was supposed to be developed in Tournai. The uplifted Kaczawa block was supposed to deliver epimetamorphic and tectonic breccia materials. Findings of Tournai, upper Visean and whole Devonian profile in the Kaczawa Nappes, at their southern vergency during the Sudety phase concluded that the said epimetamorphic detrital materials originated from the upper part of the Leszczyniec and Przybkowice units in the Rudawy Janowickie Mountains and from the crest spreading eastward in Tournai. Recently it is covered by the Kaczawa Nappes. In Tournai the crust was cut by the Dymanów dislocation, that was still developing after the nappes begun i.e. in Visean. The author compares the structural development of the lower Kaczawskie Mountains stage (after A. Haydukiewicz) with the structural development of the Bardzkie structure.
