%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.
