Volumetric activity of radon within fault zones of Kirov-Kazhim and Pechora-Kolvin aulacogens
The article is devoted to radiometric studies within the Kirov-Kazhim (KKA) and the Pechora-Kolva aulakogenes (PKA). KKA is the first-order structure of the Volga-Ural anticline, which is located within the ancient East European Platform. The PKA is located in the central part of the Timan-Pechora E...

The article is devoted to radiometric studies within the Kirov-Kazhim (KKA) and the Pechora-Kolva aulakogenes (PKA). KKA is the first-order structure of the Volga-Ural anticline, which is located within the ancient East European Platform. The PKA is located in the central part of the Timan-Pechora Epibaykal plate.
