Plateau ages for whole-rock samples of sericite-quartz altered rock and sericite-bearing gold ore are 285.5 ± 1.2 and 288.4 ± 0.6 Ma. Sericite concentrates gave plateau ages of 284.3 ± 3.0 (host rock) and 285.4 ± 0.2 (ore) Ma.The age of mineralization is slightly younger than a U-Pb zircon age of 296.7 ± 4.2 Ma obtained for the postcollisional Djangart granite, about 80 km southeast of Kumtor, and slightly older than two published U-Pb ages of 268 ± 1 and 280 ± 9 Ma on a postcollisional granite intrusion about 10 km west of Kumtor. These ages also overlap with data from the other major gold deposits of the 2,000-km-long southern Tien Shan fold and thrust belt. The ages define a late Paleozoic event of gold mineralization related to regional-scale fluid flow and granite magmatism controlled by transcrustal shear zones during the postcollisional stage.
