The 6th congress of the Commission of the Geological-Ge raphical Department of the Academy of Science was held at Sverdlovsk from May 22 to May 27, 1957. The three principal method of determining the age of uranium -thorium - lead, uranium -thorium- helium, and potassium-argon formations were successfully applied. In addition, the method of determining the degree of enrichment of argon, potassium flame photometry, and the process of determining the smallest quantities of lead were considerably improved. The age of rock could be determined at 1900 million years for North Karelia and for some parts of the Ukraine at 1600 to 2000 million years. In the Caucasus 4 sections were investigated the age of which fluctuates between 15 and 400 million years. (TCO)
