Natural radioactive element content of the old crystalline rocks in Southern Transdanubia (SW Hungary)
On the basis of systématisation of several thousand radioactive element content analyses made in laboratories since the 50's, U and Th content of old granitoid rocks of Southern Transdanubia proved to be much higher than the average U and Th content of granitoids in the world. This value of roc...

| Summary: | On the basis of systématisation of several thousand radioactive element content analyses made in laboratories since the 50's, U and Th content of old granitoid rocks of Southern Transdanubia proved to be much higher than the average U and Th content of granitoids in the world. This value of rocks from areas west of Mecsek Mountains as well as near Szalatnak village and Pecs city is twice higher than the world average. Areas west of the Mecsek Mountains show higher U and lower Th contents than areas east of these mountains. Uranium accumulation is higher in aplites and hydrothermal formations than in granites. The western and eastern granites are less and highly sensitive to leaching, respectively. The intensive U migration resulted in significant U accumulation in young sediments in some places. |
