Abstract
The article deals with the granitoid magmatism in the territory of Frolovskaya megadepression. Granite massifs are usually confined to erosion-tectonic ledges of the foundation, located in tectonically active zones, usually with increased heat flux. The detection of such massifs allows to predict the development of improved reservoirs in the zone of contact with sedimentary cover rocks. The age of granitoids is the Middle-Late Paleozoic. We clarify the boundaries of granitoid massifs and distinguish new massifs based on new information on geology and seismic survey. Also we analyses the connection of temperature, productivity with granitoids and foundation blocks.

Summary
Рассматривается гранитоидный магматизм на территории Фроловской мегавпадины. Как правило, приурочены к эрозионно-тектоническим выступам фундамента, расположены в тектонически активных зонах, обычно с повышенным тепловым потоком. Выявление таких массивов позволяет прогнозировать области развития улучшенных коллекторов в зоне контакта с породами осадочного чехла. С учетом новой информации по геологии и сейсморазведке уточнены контуры гранитоидных массивов, и выделены новые массивы. Проанализирована связь температуры, продуктивности с гранитоидами и блоками фундамента. THE GRANITOID MAGMATISM IN THE TERRITORY OF FROLOVSKAYA MEGADEPRESSION OF WESTERN SIBERIA.
