Abstract
Fluid inclusions in quartz and lazulite (Mg,Fe2+)Al2(OH,PO4)2 were studied for the first time in the quartz‒lazulite‒hematite-tourmaline veins of Mt. Chernaya, the Nether-Polar Urals. It was found that they are very similar. Homogenization of the most inclusions occurs at 155‒220°C in lazulite and at 147‒235°C in quartz; and salinity varies between 12.5‒15.0 and 10.7‒15.7 wt % NaCl eq., respectively. The eutectic temperature of the water‒salt solution in both cases ranges within ‒31 … ‒40°C, which indicates the presence of magnesium, sodium, and iron salts in the mineral-forming fluid. The gas phase of fluid inclusions is represented by carbon dioxide and nitrogen in approximately equal proportions.
