, first melting temperature; , melting temperature of hydrohalite; , melting temperature of final ice; , total homogenization temperature; Brt, barite; Cal, calcite; Dol, dolomite; Q, quartz; Sp(a), fine-grained sphalerite from hydrothermal stage I; Sp(b), coarse-grained sphalerite from hydrothermal stage II; Notes. Salinity (wt.% NaCl equivalent) estimated by final ice melting temperature () of type I inclusions (Bodnar, 1993) [13]; Salinity (wt.% NaCl + CaCl2 equivalent) estimated by , , and of type I inclusions by using the Software Package Fluids (Steele-MacInnis et al., 2010) [16]. Bulk density of type I inclusions estimated using the equations of Bodnar (1993) [13]. Dominant aqueous-salt species concluded on the basis of and the microthermometry behavior of fluid inclusions. |
