Abstract: Th-U-Pb dating of monazite confirms the Permian age 278±11 Ma of rhyolite tuff in the Northern Gemericum. This rock was a protolith for stratiform U-Mo mineralization formed during the Late Permian by ground water. The Permian formations and stratiform mineralization are cut by younger vein and stockwork mineralization near Novoveska Huta and Krompachy. The quartz vein with uranium mineralization in Krompachy is accompanied by albite, rutile, sulphides, xenotime-(Y) and rare monazite-(Ce). Th-U-Pb dating of the vein monazite gives the Cretaceous age 124±10 Ma of remobilized vein uranium mineralization.
