Behavior of the main rock-forming elements, tungsten and molybdenum during the interaction of granite melt with dolomite at 700 oC and PH2O= 1 kbar in the presence of fluorineстатья
Аннотация:The experiments conducted simulate the formation of magnesian skarns. Their main feature is the formation of reaction metasomatic formations during the direct interaction of granite F-containing melt and carbonate, represented by dolomite. Skarn zoning of the magmatic stage of interaction of aluminosilicate melt and carbonate rock was experimentally simulated. The behavior of the main rock-forming (Si, Al, Ca, Mg, Na, K), rare elements (Mo and W) and fluorine in all zones of the column was studied and their mobility under experimental conditions was estimated. The similarity of the metasomatic column structure and mineral composition of the zones obtained in the experiment with those formed in magnesian skarns is shown.
