Conditions of localization of Mesozoic auriferous metasomatites in crystalline base of Central Aldan region

We investigated the distribution of electron hole centers produced by natural radioactivity in arkoses and their principal components (quartz-feldspar intergrowths, white and smoky quartz, and feldspars) using the electron paramagnetic resonance method. The relation between the concentrations of the Ecenters and uranium content in the rock provides information on the genetic characteristics of uranium mineralization. —Authors.
