... varied between −26° and −21°C ( Table 2 ), indicating that the dominant salts were NaCl and KCl. Eutectic temperatures of type Ia inclusions in Cu-Zn-Sn veins could not be determined due to the small inclusion size.

Then, during temperature recovery, initial melting was observed 500 between -26.4 °C and -19.5 °C (eutectic temperature), indicating that the fluid phase belongs to 501 the H2O-NaCl-KCl system (Davis et al. 1990). Final melting occurred...

... runs with comparatively low a H2O since reactions 1 and 2 require H 2 O to react with the platinum chloride salts to form HCl. The phase relations of HSL ± vapor for NaCl-H 2 O, KCl-H 2 O, and KCl-NaCl-H 2 O systems are well established ( Bodnar et al. 1985 ; Chou 1987 ; Driesner and Heinrich...

In the sylvite-and halite-bearing inclusions, sylvite was the first phase to melt between 50 and 157°C, whereas halite melted from 130 to 281°C, as can be inferred from the H 2 O–NaCl–KCl diagram in Figure 8 . On the basis of these data, we contend...
