COMPARATIVE CHARACTERISTICS OF THE TIN-BEARING GRANITOIDS OF DIFFERENT AGES OF THE SOUTH PRIMOR'YE AND CERTAIN OTHER TIN-BEARING AREAS

A comparison of the petrogeochemical characteristics of tin-bearing granites of different age of South Primorye, the Khabarovsk region, and other tin-ore areas, is given. It is shown that in the regions studied tin is usually contained in the most highly acid, potassium-enriched differentiates of multi-phased intrusive complexes, in the formation of which hybridization processes played a considerable part. Data shows that the tin-bearing granites occurring in different structural facies zones as well as granites of different age developed in one and the same province show characteristic petrochemical peculiarities in addition to many other features they have in common. — Auth.
