Аннотация:—New data on the fission track ages of apatite detrital grains from Eocene–Miocene deposits of dif�ferent ages in the Kronotskii Peninsula and the Tyushevka (Tyushevsky) Basin, Eastern Kamchatka are given. The data obtained give us grounds to distinguish three age groups of apatite grains: 31 ± 5, 11–15, and 6–9 Ma. The exhumation ages of sedimentary complexes containing the studied apatite grains are compared with the times of the main tectonic events in Eastern Kamchatka. It is concluded that the collision processes contin�ued from the Oligocene to the Late Miocene
