Abstract

On the Pauzhetka geothermal field the mineral deposits which are formed, when dumping thermal water of separators of wells, are allocated. Compositions, structure and geochemical properties of this precipitation on pro-deleting and in vertical slits of “raincoats” are studied. It is established that they are put X-ray amorphous mordenite – opal mixes (in the beginning dumping of thermal waters), further precipitation becomes completely siliceous. The zeolitic component of mineral deposits defines their high sorption properties in the relation of Au, Ag, Hg, As, Rb, Sr, Ba, Cs, etc. elements; in a mordenitovy matrix sulfides of iron, silver, copper are formed. It is shown that the mineral deposits which are formed on the day surface of the Pauzhetka geothermal field are the indicator of alkaline mineral- and the ore-forming processes on the lower horizons of the Pauzhetka hydrothermal system.
