Abstract (in english)
   Based on the K-Ar muscovite/illite and Rb-Sr sphalerite dating, base metals and uranium mineralization of the Bohemian Massif originated during (1) the Westphalian and Stephanian, (2) Lower to Middle Permian, and (3) Lower Triassic periods. The origin of the first stage of mineralization can be related to the short period of post-collisional collapse and extension of Variscan belt. The second stage of mineralization is related to the late Stephanian and Permian transpressive-transtensive reconstruction of the Variscan crust and the third stage coincides with the period of Mesozoic reactivation of brittle structures.
