Isotope age of zircons of metamorphic formations of Tien Shan
Description
Results of U-Pb and Pb-Pb determinations of age of zircons of metamorphic layers of Tien Shan, subjected to obvious and concealed contact action of intrusions tearing them are presented. It is shown that construction of discordance in these cases presents intrusion age as the true one
