Abstract
According to U-Pb dating, the granitoids of the Tyrma-Bureya complex in the northern Bureya-Jiamusi superterrane of the Central Asian Fold Belt are not of Paleozoic, as previously thought, but of Mesozoic age (Nizhnyaya Stoiba massif, 218±2 Ma; Talakanka and Ust'-Dikan massifs, 185±1 Ma). They formed at the early stages of collision between the North Asian and Sino-Korean cratons and the intervening Amur superterrane.
