Abstract
A few volcanic structures have been investigated during the practical training programs in the area of Arshan (Irkutsk Region, Russia) and Nanjing (East China). The purpose of the study has been to collect the field material and perform a comparative analysis of the causes of the volcanic structure formation in the study areas. The volcanic activity has been characterized in geological and tectonic terms, and causal relationships between its intensification and structural confinedness have been defined. The research methods include field studies, as well as the analysis of literary and archive materials. The main achievement of the research is the determination of the global cause that influenced the volcanism of the territories. According to the authors, the commonality of the characteristics is to a large extent due to the consequences of the India-Eurasia collision.

Summary
Внутрикоровые разломы Тункинского рифта Оливиновые толеиты, базаниты, щелочные базальты, гавайиты растяжения – компенсационные структуры. Большая часть раннекайнозойских базальтоидов представлена толеитами, но в некоторых ареалах преобладают щелочные оливиновые базальты и базаниты [5]. Нанкин располагается вулканический парк Лухе, в пределах которого наблюдаются наиболее крупные вулканические структуры: Ваншань, Лингуаншань, Губашань, Гуйцзишань. 4 представлен вулкан Гуйцзишань (Гуйцзи), который активизировался в плиоцене – плейстоцене. Характерные вулканические горные породы региона – толеиты, щелочные оливиновые базальты, базаниты 1 – кайнозойские базальты; 2 – вулканы; 3 – границы блоков; 4 – главный разлом; 5 – река и озеро Fig. 3. 1 – Cenozoic basalts; 2 – volcanoes; 3 – boundaries of the blocks; 4 – main fault; 5 – river and lake.
