Our EBSD pyrite data suggest this process recrystallized the original py 1, as both py 1 and py 2 phases share the same crystal orientation, and therefore together they form single crystals. An oxidized ( 45 log f O 2 ) and acidic fluid can transport Zn as Z n C l 4 2 − complexes across a range of pH values (0–~9).
