228 Summary bution of the mineral successions within the ranges of strike directions makes the zonal structure of the floors of the deposit also distincly visible. Furthermore, it can be seen from the diagrams of mineralization, that the deepest mine open- ings lie in the zones III and IV, as the most favourable eonditions of minerali zation prevailed there. In the direction of the marginal areas there appears a parallel decrease in the intensity of vein tectonics and mineralization. Caused by the more recent teetonic stress pattern of the second cyele of minera lization there occurred, especially on the vein fissures of the Hercynian direction and the west—east direction, a paragenetic “addition of a floor”, which caused, in certain places, an improvement of the eonditions of mineralization on the veins.
