Description
New results of radiometric dating of Sinec (Rimavica) granites by U-Pb and K-Ar method are presented. The K-Ar method (muscovite and biotite) gives the age of 94 m.y., which can be interpreted by tectonics. The U-Pb dating of zircons gave a concordant age of 350±5 m.y., which is a more reliable age than the one obtained from the same samples by Rb-Sr isochrone. The increased age of the Sinec (Rimavica) granites determined by the Sb-Sr method could be caused by the supply of radiogenic Sr from the surrounding older metamorphic rocks to the granites during retrograde metamorphism synchronous with granite autometasomatism.
