geotermija vengrii. Features

you are: geotermija vengrii

It is possible to explain all these features a dome-shaped raising partially fused astenosfery (thermal mantijnyj diapir) under the Pannonsky hollow. From the point of view of tectonics it is very important to investigate time of development of it diapira and process of its formation. It is supposed, that in an interval of time from an average oligotsena to early miotsena the area of the Pannonsky hollow and Internal Carpathians represented a zone subduktsii oceanic - a suboceanic bark of trench Magura. subduktsija occurred along a belt Lenin klippov and has led to strong deformation of a belt klippov and areas of External Carpathians. The plunging plate induced konvektsiju in the top cloak. Modelling calculations have shown, that konvektsija can promote carrying out of enough of heat for partial fusion bottom litosfery over a plunging plate. Risen hotter mantijnoe the substance moved lateralno in the basis of a bark of Pannonsky area and Internal Carpathians, assimilating a bark and places piercing it, that has led to outpouring of the big weights andezitriolitovyh lavas. Petrologichesky and geochemical features of izvestkovo-alkaline volcanic breeds of Pannonsky area and Internal Carpathians will be co-ordinated with theoretical representations about their origin. When in the end of an average miotsena subduktsija has come to the end, in the field of pressure of region the stretching began to prevail. Thin, but for the present the continental bark has started to plunge, and the arisen deflection began to be filled with a powerful layer pliotsenovyh and chetvertichnyh deposits. Pliotsen-plejstotsenovyj basalt vulkanizm, most likely, it is connected with a region stretching. The assumption about mantijnom genesis of the Hungarian basalts has been stated and on the basis of the microanalysis lertsolitovyh inclusions in these breeds. Owing to konduktivnogo relicts thermal mantijnogo diapira can be found out coolings and now.
