Description
Lead contents of barite coexisting with galena from the Senzai vein, Oe mine, Hokkai-do, lie in a comparatively narrow range from 120 to 290 ppm (or 9×10-5 to 2×10-4 mole fraction) in PbSO4 content. Combining these data with fluid inclusion studies and phase equilibrium studies, the possible physicochemical conditions of the Senzai mineralization were estimated.<BR>The results are as follows:<BR>(1) Formation temperature: 180°-230°C<BR>(2) Oxygen fugacity: 10-40.3-10-35.7 atm<BR>(3) Sulfur fugacity: 10-13.8-10-11.6 atm<BR>(4) Carbon dioxide fugacity: 10-1.5-10-0.4 atm
