Endogenous regimes and uranium metallogeny of the erzgebirge and central France ore districts

The paper characterizes the geology, deep structure, and endogenous regimes of evolution of the main tectonic elements of the Central European Variscides. On the basis of these data, we compared geological settings; principal structural features; and intensities and styles of regional metamorphism, magmatism, and postmagmatic activity at various stages of formation of two uranium ore districts: (1) the Erzgebirge district, within the Erzgebirge-Fichtelgebirge anticlinorium in the northern sector of the Bohemian Massif, and (2) the Central France district, in the frames of the Massif Central, France. The causes of different tin and uranium ore potentials are considered for these two districts, which are similar in many geological features.
