The age relations of granite intrusions of the Ukraine were investigated by using the argon method. New data are reported on the age of magmatic rocks of the Northern Caucasus. The effects of the emanation of radioactive elements from minerals on the determination of the absolute geological age were investigated. A comparative analysis was made of the leaching of uranium and radium isotopes from uraninite. The emanation capacity of uraninite was investigated with respect to radon, thoron, and actinon as a function of temperature. The distribution of radioelements in different sections of uraninites was investigated. A new method is reported for separating small amounts of lead, and a procedure is described for the determination of ionium. A roentgenometric study was made of the suitability of monazites for the determination of geological age. The occurrence of inert gases in meteorites and their isotope composition was investigated. The variations of neutron flux on the surface of the earth were investigated. Data are reported for the Soviet scale of (geologic) chronology. The argon method is investigated for determining geologic age. The isotope composition of uranium in meteorites was investigated. An investigation was also made of the actiniumradium ratio in minerals. (W.L.H.)
