The U and Th distribution in various types of alkaline rocks of the Ural and South Mugodzhary was studied. For most of the investigated massifs the thorium content was near the average thorium content in the earth's crust, but the uranium content is heightened in comparison to the earth's crust. Variations of thc Th/U ratio are entirely connected with the change of the U-content. A direct correlation of the contents of radioactive elements with rare earths and to a smaller degree with Nb and Zr was established. (auth)
