Abstract
ON THE NECESSITY OF DRILLING A FEW DEEP STRUCTURAL BOREHOLES IN THE LOWER SILESIA REGION
Summary
Necessity of drilling deep structural boreholes in the areas of the Sudety Mts and Fore-Sudetic block is discussed. The boreholes should be made in order to: (1) reveal existence of second-order domes situated within well-known Variscan granitoids intrusions of the Karkonosze, Strzegom - Sobótka, and Kłodzko - Złoty Stok areas, beneath metamorphic covers, (2) found out whether or not inferred "blind" intrusions of Variscan granitoids actually occur in the eastern part of Strzelin Hills, in Bystrzyckie Mts, Śnieżnik Crystallinicum, and in the Fore-Sudetic block, and (3) drill through Moldanubic gneiss block of the Sowie Góry Mts, delineate westward extent of these gneisses, recognize deep structure of Łomnica plain (Bystrzyckie Mts) anticlinorium and of Štrenberg - Horbobenešov (western Sudety Mts) zone, characterize nappe structure of the Bialskie, Złote and Śnieżnickie Mts. as well as to recognize deep structure of the Bolków - Wojcieszów anticlinorium. The data supplied by these boreholes would make a basis for prospecting endogenic ores in the above mentioned structural units.
