| Abstract |
At present there are several models with the help of which an attempt is made to explain some elements of the mechanisn and formation conditions of the Pauzhetka hydrothermal system. In modelling there appear difficulties connected with the incomplete character of initial data, as regards the physical properties of the medium and the uncertain space boundaries within which the hydrothermal process takes place. From this point of view, the 2-dimensional profile thermal hydrodynamic models based on the conservative mass and energy equations and on water flow movement equations are the most effective. Applying these models to the Pauzhetka hydrothermal system, we have established that (1) A shallow magma body with the anomalous temperature of 700-10OO0C and with a volume of 30-50 lun3 may be the heat source for the Pauzhetka hydrothermal system and the Xambalny steam jets. (2) The water feeding source of the Pauzhetka hydrothermal system and the Kambalny steam j e t s may be meteoric waters which areinfiltrtedat an average rate of 5-10 kg/s* km?. It is possible, on the basis of thermal hydrodynamic models, to try to find explanation of the conditions of formation of ore deposits directly connected with the magma chambers; it is necessary also to compare thermal hydrodynamic models with hydroisotopic and hydrochemical data. |
