Реферат: rus: Описана модель мантийного термохимического плюма, и представлена схема его зарождения на границе ядро-мантия. Приведены основные соотношения для определения тепловой мощности термохимического плюма и диаметра его канала. Плюмы с грибообразной головой имеют относительную тепловую мощность 1.9р=1410 °C и T р=1380 °C. Расчеты толщины слоя остаточного расплава проведены для Хэнтэйского плюма, у которого толщина головы l = d =29 км ( d - диаметр канала плюма). На основе предложенной модели плюма с грибообразной головой в результате расчетов может быть получен нормативный состав расплава, близкий к составу нормальных гранитов.
eng: The model of a thermochemical mantle plume is described. The scheme of origination of the plume from the core-mantle boundary is presented. The basic ratios for determining the thermal power and the diameters of thermochemical plumes are given. After eruption of the melt from the plume conduit to the surface, melting occurs along the base of the crustal block above the plume roof, resulting in the formation of a mushroom-shaped head of the plume, which means that a large intrusive body (deep-rooted batholith) is formed. The relative thermal power of such plumes is 1.9melt=1410 °C and Tmelt=1380 °C. The thickness of the residual melt is estimated for the case of the Khentei plume. Its head’s thickness ( l ) is equal to the plume conduit diameter ( d ): l = d =29 km. The proposed model of the plume with the mushroom-shaped head was used to calculate the normative composition of the melt with a chemical composition similar to that of normal granites.
