Аннотация

The paper reports the results of petrological calculations of some generations of rock-forming (pyroxene, amphibole, biotite) minerals and accessory minerals (zircon and apatite) from the Mesozoic igneous rocks of the poorly studied Dzheltula alkaline massif. It is the largest magmatic structure of the Tyrkanda ore region, located in the eastern part of the Aldan-Stanovoy shield. Obtained results of identification of physical-chemical conditions of pyroxene, amphibole and biotite crystallization indicate the fact, they were formed at various temperatures and at two deep levels. Based on the study of typomorphic features of accessory minerals (zircons, apatites) it is concluded that, during formation of the Dzheltula massif, two sources existed - of mantle and crust nature. It is concluded that, petrological characteristics of rock-forming and accessory minerals from the rocks of the Dzheltula massif reflect features of deep structure of the Earth’s crust. Obtained data indicate that, the typomorphism and chemical composition of zircons and apatites reflect formation conditions, features of host igneous rock composition and their geochemical specialization for such elements as U and Th.
