%0 Journal Article %T Geological, structural and mineralizing aspects of renewal of exploitation on the strieborn¨¢ vein in the Roznava ore field %A Sasv¨¢ri Tibor %A Jan£¿ura Mari¨¢n %A Ma£¿o £¿uboslav %J Acta Montanistica Slovaca %D 1996 %I Technical University of Kosice %X In the Ro ¨¾ava ore field the ore-bearing vein structures were probably originated in transstensional regime of the sinistral shear zona of NE-SW diection. The consequences of strain regime manifest by extensional duplexex in the near-surface parts of the terrestrial crust. The Srieborn¨¢ vein was successively reworked by the 11 deformational phases and mineralizing stages. Several types of textures and accumulations of sulphidic ores occur in the quartz - siderite vein. The most significant ore accumulations are present within and along the reactivated subvertical fault systems with high - grade ores; these are focus into pinch and flattening zones of asymetric siderite boudins of the Strieborn¨¢ vein. %K silver vein %K extensional duplex %K subvertical faults %K tetrahedrite mineralization %K Roznava ore field %K Slovakia %U http://actamont.tuke.sk/pdf/1996/n1/9sasvari.pdf
