New zircon ages for the rocks, evidencing the occurrence of Paleozoic intrusive magmatism in the zone of the Fore Range and the Bechasyn zone of the Greater Caucasus, are obtained using the U–Pb LA-ICP-MS method. The age of the intrusions of the Kuban group of the Malka granite plutonic complex (the Bechasyn zone) is estimated at 309 ± 2 Ma by the example of the Indysh granodiorite intrusion. The U–Pb zircon age of 354 ± 2 Ma for the granites from the Beskes massif (the Fore Range zone) was obtained for the first time. The U–Pb zircon ages obtained correspond to magmatic events (processes) recorded in the pre-Jurassic Greater Caucasus during the Carboniferous.
