Abstract
U–Pb (ID-TIMS) geochronological studies of garnet from iron-magnesian metasomatites of the ore occurrence of the Kurung-Hoonku River area (Legliera group of deposits, West Aldan megablock) were carried out. The results obtained (1901 ± 5 MA) are first age determination of formation ore-bearing iron-magnesian metasomatites on the Aldan shield. It show their connection with the final stages of the Early Proterozoic tectonic-magmatic evolution of the Aldan geoblock.
